Series 6: The War Games

The TARDIS arrives in what appears to be a World War I battlefield, The Doctor along with his companions Zoe Heriot and Jamie McCrimmon. Avoiding an artillery barrage, they encounter Lady Jennifer Buckingham, a friendly nurse, who takes them aboard her ambulance and explains they are in No Man’s Land. However, they make little progress before a German squad ambushes the vehicle. The situation is reversed moments later when a British squad led by Lt. Jeremy Carstairs liberates the ambulance. He confirms the year is 1917 and they drive on to the nearest British base where the Doctor and his friends are entrusted to the base commander, Major Barrington, who in turn decides to send them on to the controlling officer for the area. Left in the trenches, Carstairs and Lady Buckingham start to talk and realize there are some mysterious gaps in their memories.

The commanding officer General Smythe, who is based at a nearby chateau, is rather enigmatic and secretive. He has a secret communications device in his chambers through which he requests a further 5000 specimens for his section, and also seems to be able to disappear for short periods from his private quarters. His subordinate, Captain Ransome, questions him on this behaviour and Smythe responds by donning a pair of glasses and exerting some sort of mental control over Ransome to make him forget what he has seen. When the Doctor and his companions are brought before him, Smythe decides to hold a court martial, producing a distorted report on their activities since arriving in the trenches. The Doctor tries in vain to challenge this version of events, calling Carstairs and Lady Buckingham to offer evidence in his defence, but Smythe has made up his mind. When the military judges retire to consider their verdict, Smythe uses his hypnotic abilities to persuade Barrington and Ransom to agree that the prisoners should be punished; Jamie is to reassigned to his “regiment” for further court martial; Zoe will be incarcerated for ten years as a spy; and the Doctor himself will be shot. The trio are separated as they await their fate.

During the night Zoe sneaks away from Lady Jennifer, under whose protection she has been placed, and starts to investigate the chateau. She manages to free the Doctor, but before they can escape Ransome finds them and announces the execution is imminent. With Zoe made to watch, the Doctor is attached to a firing post, and the firing squad prepare to fire.

The execution squad is interrupted by a sniper, allowing Zoe to free the Doctor and they flee to the military prison where Jamie is being held. He has meanwhile found himself in a cell with a redcoat apparently from the Battle of Culloden (although he gives the year as 1745 and not 1746), who claims to remember little after being abducted from the scene of the battle. Overcoming mutual enmity, they eventually stage a mock fight as a distracting ruse which enables an escape bid. The Doctor has meanwhile gained entry to the prison by posing as an Examiner from the War Office, totally confounding its commandant, Gorton. The escape attempt is reported as is the death of one of the escapees, but it is not Jamie and he is soon brought to Gorton’s office for interrogation by the “Examiner”. The Scot plays along but after a while Gorton becomes suspicious and has to be knocked out to protect the ruse. The reunited trio make to leave but soon find themselves once more prisoners of Captain Ransome.

Back in the Chateau, Smythe’s mysterious behaviour has continued and he departs for a military conference in a cupboard-like box which has materialized in his quarters. It departs in the manner of a TARDIS with Smythe inside. Ransome has witnessed this, but once more Smythe’s hypnotic powers erase the event from his memory. Elsewhere in the building, Carstairs and Lady Jennifer talk more freely, mentioning a strange mist they have both encountered. They all voice concerns about the behaviour of Smythe at the court martial. Ransome returns with news of the recapture of the prisoners, but by this time Carstairs has become so concerned at the situation that he and Lady Jennifer decide to help the three prisoners. She distracts Ransome while Carstairs sets the trio free. Jamie tells the others of the redcoat, while Zoe now reports on the strange apparatus in Smythe’s office, prompting them all to decide to take a closer look. With Ransome out of the way the Doctor and his friends investigate Smythe’s office and see the communications unit – though curiously neither Carstairs or Lady Jennifer can see it initially, evidently their minds being clouded. The Doctor realizes the unit is active and disables it, though not before Smythe and a technician at the other end have observed their interference.

The Doctor and his party now make to leave in the ambulance, once more evading the hapless Ransome by Carstairs’ quick thinking that he is taking the prisoners for further interview with Smythe in another location. When Smythe returns, he is furious with the Captain for allowing the prisoners to escape and immediately orders surveillance of the departing vehicle. It is eventually found heading eastwards in sector four. Smythe appals Carstairs by ordering that British troops fire on an ambulance with two women inside. To avoid the shelling, the fugitives drive into a strange mist which soon engulfs them and makes Carstairs and Lady Jennifer very nervous. The Doctor takes over at the wheel and drives on into a valley where they all disembark. They are there greeted by a very strange sight indeed – a phalanx of Roman soldiers is advancing on them with weapons drawn.

Fortunately the ambulance starts again in time and the party drive away, leaving the Romans bewildered. In the ambulance, the Doctor deduces they have passed through some sort of force-field barrier which is keeping time zones apart, and speculates there may be many such zones on the planet. He decides to try and get a map of the area but the only place he can think of to locate one is at Smythe’s office back in the chateau. Carstairs resumes the “prisoners and escort” routine to get them all back into the Chateau, where Ransome challenges them but is overpowered and tied up. The Doctor searches Smythe’s quarters and there uses explosives to blow open the General’s safe. This alerts a soldier to some wrongdoing, but Carstairs overpowers him. The Doctor is now able to retrieve a map, showing a series of triangles all marked with dates and names of wars in the history of the Earth. With the map in their possession, the five travelers escape in the ambulance once more – this time to cross over into German lines and be captured German soldiers.

They are all taken to the German military HQ where the Doctor is interrogated by the impressionable Lieutenant Lucke. The Doctor tells him the truth about his travels, and illustrates his technological power by using the sonic screwdriver. However, just as the Doctor is about to make a breakthrough the commanding officer, Captain von Weich, arrives. The Captain takes Lucke to one side and, donning a monacle, exerts the same sort of mental control of his soldier that General Smythe did with his men. Von Weich stalks away to report the capture of the fugitives via a communications unit, and reports they claim to be time travelers. Lucke returns to the prisoners and the Doctor succeeds in breaking the mental conditioning and soon gets hold of the Lieutenant’s weapon. He uses this to get the Lieutenant to take them back to the ambulance and, free once more, the Doctor and his friends decide to head toward a mysterious black triangle marked on the centre of the map.

This zone is indeed Central Control and is populated by technicians in neutral futuristic clothes and strange glasses. Smythe is there too and welcomes the arrival of his superior, the War Chief, who brings greetings from his own superior, the War Lord. News arrives from von Weich that the prisoner have escaped again and the War Chief is especially concerned that the fugitives claim to be time travelers. It soon becomes apparent that they are involved in some sort of war game using models to plot real conflict between the rival armies.

The ambulance has meanwhile reached the American Civil War zone. They are soon besieged by Confederate troops and Carstairs is separated from the others and taken as a prisoner to Central Control. The ambulance drives on until it runs out of fuel. The Doctor, Jamie, Zoe, and Lady Jennifer take refuge in a barn and try to get some rest. They are hidden, however, when one of the travel units materializes in the barn and a stream of Confederate soldiers pour out, heading outward to battle. The Doctor and Zoe examine the capsule but while they are inside the door slides shut and the machine dematerializes.

The Doctor and Zoe soon arrive in a docking bay for the TARDIS-type vehicles located in Central Control. They soon find some German soldiers for the First World War zone and then a Roman legion, all in deep hypnosis. The pair adopt the eye glasses of the alien beings managing the war zones and they use this disguise to explore the Central Control area. It is a vast building and they soon find themselves in a lecture hall for a presentation, where they have their fear that the war zones are on an alien planet confirmed.

Jamie and Lady Jennifer have meanwhile become embroiled in a battle between Union and Confederate soldiers which the latter forces win. However, the head of the Confederate forces is Von Weich, now wearing the appropriate uniform, and he denounces the pair as spies and has them restrained. This capture is reported to the War Chief, who instructs that they be held until they can be reprocessed. The War Chief has been in dialogue with the Chief Scientist, a nervous man preoccupied with improving the mental conditioning process to eliminate the 5% failure rate. Back in the barn Jamie and Lady Jennifer are freed by a union soldier named Harper and escape but all three are soon recaptured. It seems Harper is one of those on whom the mental processing has failed, and is also part of a broader resistance movement. A little later a squad of resistance soldiers bursts in upon the barn, seizing control and restraining von Weich.

The Doctor and Zoe witness an experiment in mental reconditioning with Carstairs as the subject. The Chief Scientist explains to his audience that technology improvements will enable even the most resistant specimens to be reconditioned. Carstairs is reconditioned successfully and immediately denounces the Doctor and Zoe as German spies. Based on this, the Scientist incorrectly infers that the conditioning hasn’t been successful and the Lieutenant is restrained and taken away. The Doctor now examines the apparatus and realizes it can be used to de-process as well as condition the human subjects. The War Chief visits the presentation and clearly recognizes the Doctor amongst the crowd, prompting the Doctor and Zoe to run for freedom. She gets separated from the Doctor but soon runs into Carstairs – who draws his revolver to shoot her.

The Chief Scientist interrupts the situation and ensures Carstairs is disarmed, still believing him to be disturbed, and then imprisoned once more. She is interrogated by the Security Chief, another of the alien leaders, who discovers her history using a futuristic lie detector. When the War Chief calls in on the interrogation, it is clear that he and the Security Chief are not easy bedfellows.

Meanwhile the Doctor finds the Chief Scientist and persuades him he is actually a devoted student, offering to assist with his work on the mental conditioning process. He persuades the Scientist to de-process the dazed Carstairs and once this is done the Doctor and the Lieutenant overpower the Scientist.

In the American barn the resistance fighters are squabbling amongst themselves, unclear of the origin of the situation. The only thing that calms the situation is the arrival of their leader, Russell, a British Boer War soldier, who asserts his authority. Von Weich uses the confusion to try and send a message to Central Control, but succeeds only in demonstrating to the resistance fighters that there is a hidden communications device nearby. Von Weich then manages to activate the emergency alarm on the apparatus.

Back in Central Control, this is relayed to the War Chief and the Security Chief, and they leave Zoe while they go to investigate. This enables the Doctor and Carstairs to rescue Zoe, while also being able to scan through the files of known resistance fighters and those on whom processing failed, alerting them to the existence and extent of this movement. However, it is also clear that not all the possible resistance are organized into a single force. They then head to the security centre and observe the Security Chief decide to respond to the emergency in the American Civil War Zone by sending a squad of troops to investigate in one of the travel machines. The troops are sent to the barn where they emerge and open fire, killing Harper, but Russell and his troops fight back and overpower the attacking troops. Russell now decides to take the fight to Central Control and outlines plans to use the travel machine to take a troop of resistance fighters to attack them. Jamie reluctantly agrees to accompany them, while Lady Jennifer is sent to the rebel HQ to help with the wounded resistance fighters, and Von Weich is left under guard in the barn.

Meanwhile the enmity between the Security Chief and the War Chief is mounting, made worse when they realize Zoe has escaped, Carstairs has disappeared, and the Chief Scientist has been overpowered. It also seems the War Chief is not of the same species as the other aliens controlling the war games and the Security Chief, realizing the fugitive pair have a knowledge of time travel and are thus probably somehow related to his rival the War Chief. The War Chief himself happens to be at the security center when news of the approaching traveling ship reaches them. He assembles a patrol of guards outside the docking station and when Jamie, Russell and the other resistance

The bodies are removed and taken to the Chief Scientist for reprocessing, while the Doctor and Zoe watch on from a secret hideout. Jamie is identified as having never been processed and is taken away for further examination by the Security Chief while the reprocessing effort begins in the laboratory. The Scientist is stunned when the Doctor appears at his side offering to help with this process, but again it is a ruse to overpower him. He revives Russell and the others, explaining his friendship with Jamie, and the band of rebels now plan to escape the control center with the Doctor and Zoe. The Doctor realizes Zoe can be of immense use having memorized the faces of each of the resistance leaders from the various war zones. It is decided to try and pull together the disparate resistance fighters into a single fighting force. The next task is to rescue Jamie from the security center and, this accomplished, they all make it to the docking station. The Doctor sends Zoe, Russell and the resistance fighters back to the war zones in a travel machine to pull together the rebel army while he, Jamie and Carstairs stay in Central Control to try to get hold of the processing equipment. When Russell’s party returns to the barn they realize Von Weich is bidding for freedom, having reconditioned his guard, Private Moor. However, they arrive just in time and Moor is able to resist once more, ending up shooting Von Weich dead.

The Security Chief is becoming obsessed with thoughts of a conspiracy between the Doctor and the War Chief. This lack of attention enables the Doctor to get back to the processing room where he steals the processing equipment. He and his friends return to the docking bay and enter one of the TARDIS-like vessels. However, the War Chief has become alert to their plans and so traps the machine and begins to manipulate and shrink its internal dimensions from outside. Inside the craft the Doctor, Jamie and Carstairs have seconds to live.

The Doctor emerges under a flag of truce, but this is but another ruse to re-enable the dimensions of the craft, which is then used to spirit the three friends away. Even more impressively, he has seized the correct circuits to allow the vessel to be independently piloted between war zones. He pilots it to the Roman zone, planning to travel on foot then to the 1917 zone where he has agreed to meet Zoe.

Back in Central Control the War Lord, leader of the aliens, has arrived to assume personal control of the situation. He is furious when he learns the extent of the Doctor’s havoc from the other war planners. They are tracking the missing vessel, named a SIDRAT, and follow it remotely to the Roman Zone. The Security Chief then tries to denounce the War Chief to the War Lord, accusing him of conspiring with the Doctor, but he dismisses this concern as unfounded.

The Doctor, Jamie and Carstairs have now reached the 1917 zone on foot, but their progress is being tracked by General Smythe, who arranges a machine gun reception for them. Fortunately Zoe and her team are able to overpower the machine gun nest but this does not prevent her three allies being taken prisoner by a patrol of British soldiers. The Doctor, Jamie and Carstairs are taken back to the chateau, where Smythe orders the Doctor’s immediate execution while the other two are assigned for reprocessing. When he reports this to Central Control, he is reprimanded for not taking all three alive and not recovering the reprocessing machine. He heads off to stop the execution, but others have the same intention. A large army of resistance fighters under Russell attacks the chateau and Smythe is just able to communicate the dire situation to Central Control before he is shot. The Doctor and his friends are now in control of the chateau, but a short while later a large force of conditioned soldiers is sent against the building, British from one side and Germans from the other. The Doctor responds by reprogramming some of the machinery in Smythe’s office, allowing a war zone with its mists to be drawn immediately around the chateau. This protects them all from attack. In Central Control, the War Lord responds to this blow by taking personal control of the entire operation.

The Doctor now uses the de-processing equipment on some captured humans and is relieved that it works. Moments later another SIDRAT arrives and a squad of alien soldiers stages a swift reprisal attack, seizing the Doctor and the processing equipment.

The Doctor is taken to central control and is interrogated by the Security Chief using the truth device. He charges that the Doctor and War Chief are both of the same race, the Time Lords, and that somehow the War Chief is planning to betray the project to his own people. The Doctor refuses to co-operate and is tortured for information until the War Chief arrives and confirms he and the Doctor are indeed both Time Lords. The War Chief then has the Doctor transferred to his own custody so that the two of them can talk, while the Security Chief fumes. The War Chief and the Doctor now talk frankly of the Doctor’s having stolen a TARDIS and absconded from his homeworld. The purpose of the war games is also revealed: the humans will be whittled down until only the strongest survive and these soldiers will then be used as an army to conquer the galaxy. The War Chief sees conquest as a means of achieving a greater peace and asks the Doctor to help him in this scheme. He of course refuses, condemning the War Chief for sharing Time Lord technology with the aliens and helping them to build the SIDRATs. The War Lord too offers the Doctor a partnership at the apex of their galactic conquest, but it is also clear the War Chief wants the Doctor to work with him alone in toppling the War Lord once the conquest is complete.

Back in the Chateau, the rebels focus on trying to assemble their resistance army using Zoe’s skill at remembering the faces identified as unconditionable. Later that night, a squad of Mexican bandits invades the Chateau and its leader, Arturo Villar, is slowly persuaded to add his force to the collective army of resistance. A council of war is held at the Chateau, with a Russian soldier named Ivan Petrov acting as the broker who finally persuades Villar to throw his troops in to the combined force. They all now work out a plan to seize a SIDRAT and fill it with a rebel army that can then be used to attack Central Control. Meanwhile small groups of resistance destroy the alien communication devices, sending the war masterminds into panic at Central Control. The rebels converge on the American Civil War zone and are waiting for a SIDRAT when the Doctor appears on the communicator, telling them he has taken control of the alien transportation system and sends a SIDRAT for them. Villar, Russell, Carstairs, Jamie, and Zoe climb aboard and the transport craft soon takes them to Central Control, where the Doctor is waiting for them. However, he is with the War Chief and the Security Chief and a squad of troops that take them all prisoner. The Doctor has sold them out to the enemy.

The prisoners are taken for processing and the War Chief and the Doctor are left alone. It seems the SIDRATs that the War Chief has built have but a limited life-span and he now wants the Doctor to help him by giving him his TARDIS. The Doctor now offers to improve the mental processing machines, and will start by reprocessing the rebel leaders. He goes to the processing room and is there confronted by a furious Villar and Russell, and the Security Chief withdraws the guards so the Doctor is left alone with the mob he has betrayed. The Doctor explains he only helped the aliens because the Security Chief threatened to wipe them all out using a neutron bomb but Villar cannot be persuaded he is an ally and attacks him. Indeed, only the timing of the War Chief’s arrival saves the Doctor’s life. The Doctor starts to “process” the prisoners – in fact doing nothing – and this ruse works well until Villar doesn’t play along and attacks the Doctor again. The Doctor’s friends now overpower the guards in the room.

Meanwhile the Security Chief reveals he has been taping the conversations between the two Time Lords and now knows the War Chief is plotting against them. He has the War Chief exposed to the War Lord and arrested. However, en route to the prison the escort is ambushed by the rebels and the War Chief is freed. They all find arms and now stage a major attack on the war planning room. The War Chief exacts his revenge, shooting dead the Security Chief during the general melee. He then reveals the SIDRATs are perishing at a rapid rate, making it impossible to get all the fighters home to Earth. The Doctor decides to stop the games nevertheless and the War Chief broadcasts to all zones telling them the war is over.

The Doctor knows the thousands of soldiers on the planet must be returned to Earth and that he cannot do it alone. Despite the warnings of the War Chief, he decides to contact the Time Lords and sends a mental appeal to them to assist. The War Chief slips away to the SIDRAT docking bay where his plan to flee ends when the War Lord appears and has his soldiers shoot dead his former ally. Moments later Villar and his troops reach the docking bay, killing more guards and taking the War Lord prisoner. The Doctor now tries to slip away, heading back to the 1917 zone with Carstairs, Jamie and Zoe in order to retrieve the TARDIS. It becomes apparent the Time Lords have arrived when Carstairs just disappears, sent back to his own time zone and planet, and a strange sound can be heard. The Doctor, Zoe and Jamie try to run to the TARDIS but their movements are slowed down and they fail to escape before the Time Lords can capture them.

The Time Lords manipulate the TARDIS containing the Doctor, Jamie and Zoe and bring it back to their planet, where the Doctor must answer for his crimes in stealing his TARDIS and fleeing his homeworld to travel the universe in contravention of Time Lord law. The trio emerge and are taken to a court chamber where three imperious Time Lords sit in judgement over the War Lord, whose trial has begun. He is charged with crimes against the humans he captured and against the galaxy for his war mongering. The Doctor confirms the case against him, denying any suggestion he too was involved in planning the games. The trial is interrupted, however, when a group of the War Lord’s personal guard break in to the chamber. The criminal now wishes to use the Doctor’s TARDIS to escape to freedom and takes the Doctor, Jamie and Zoe hostage back to the craft, threatening them if they do not co-operate with his plans. However, the Doctor and his friends evade their captors, allowing the Time Lords to assert control again. The Time Lords exact the ultimate punishment: the War Lord and his guards are dematerialized from all history as if they never existed, while their home planet is trapped behind a force-field and cut out from the rest of the galaxy.

The Time Lords now turn to the Doctor. He is formally charged with breaking the laws of time and interfering in the histories of other planets. His defense is the need to interfere sometimes to fight evil, citing the Daleks and Cybermen amongst the foes to be combated. While awaiting the verdict, the Doctor, Jamie and Zoe stage an escape attempt. The Time Lords stop them and then effect a tearful departure, returning Zoe and Jamie to their own original time zones with no memories of their time with the Doctor save for their first adventure with him. He himself is taken back to the court room and shown images of his friends being returned safely to the Wheel and Culloden respectively. The Time Lords then announce that the Doctor has convinced them that there is evil to be fought and that his own interest in planet Earth, itself a magnet for alien invasion, makes it ideal as a planet of exile for him. He will be exiled there in the twentieth century, his memory wiped of the ability to control the TARDIS, and his appearance will be changed as well. When the Doctor rejects all the facial images presented to him as alternatives, the choice is taken out of his hands. The Doctor protests in vain as his faceless body spirals into a dark void…

Series 6: The Space Pirates

Space beacons on the space lanes are being blown up and plundered for precious argonite by a gang of space pirates led by Caven, and his associate Dervish. The Earth Space Corps cruiser V-41 notices the destruction of the beacon and, with General Hermack and Major Warne in charge, sets out to apprehend the pirates. Another beacon is destroyed despite their best intentions, and the fragments are stolen using rocket propulsion. Hermack deploys troops to all nearby Beacons to prevent another robbery.

The TARDIS crew has arrived on Beacon Alpha Four shortly before the pirates reach it. Caven and his men mop off the security force on the Beacon, and the pirates seal the time travellers in part of the Beacon before blowing it to pieces. Fortunately the beacon falls into discrete, sealed pieces and the Second Doctor, Jamie and Zoe find themselves inside one. The eccentric Milo Clancey, in his aged ship the LIZ-79, rescues them – but they cannot retrieve the TARDIS, which is in a separate segment taken by the pirates.

The nearest inhabited world is Ta, dominated by the Issigri Mining Corporation, whose leader is Madeleine Issigri. The firm was founded by her father and Clancey, and the latter is now suspected of Dom Issigri’s murder, though nothing has been proved. Hermack visits Ta, believing that Clancey, whom he suspects of being the pirate leader, will end up there in due course – and he is right. However, Hermack leaves just as Clancey and the TARDIS crew reach Ta. Zoe has plotted the trajectory of the segments of Beacon and believes they were destined for Ta too, and as per usual the Doctor and his companions soon find the pirate headquarters. They evade capture and make contact once more with Clancey.

Meanwhile Caven forces Dervish to reroute some of the beacon fragments to Lobos, a frontier world where Clancey has his base, so as to throw suspicion on the prospector. It is clear someone has tipped him off about the Corps suspicion of Milo Clancey. Hermack and his crew see through this ruse, but it takes time, and they spend hours orbiting Lobos while the real action is taking place on Ta.

When the Doctor and his party reach Madeleine Issigri’s offices it becomes clear she is in league with Caven, and the Doctor and his friends are once more imprisoned. Their prison is the study of Dom Issigri – alive but frail and scared – and it takes time for him to recover his wits. Madeleine has meanwhile decided to break her alliance with Caven, and does so by radioing Hermack to bring his troops to Ta. Caven reasserts his authority by telling Madeleine her father is alive and threatening to kill him unless she returns to her compliant self. She responds by contacting Hermack again and telling him not to come to Ta.

The Doctor and his friends have meanwhile escaped, taking the weak Dom Issigri with them, and head to the LIZ-79. Caven has thought ahead and forced Dervish to cut the oxygen supply to the ship. As only Milo and Dom board the ship, theirs are the lives in danger, and Caven’s callousness finally convinces Madeleine to support him no longer. The Doctor, Jamie and Zoe save their friends and Dom Issigri makes contact with Hermack, persuading him of the truth of the situation.

Caven now gets desperate, threatening to destroy Ta, the Issigri base and the orbiting V-ship by means of a series of strategically placed bombs. The Doctor manages to disengage the triggering device in the nick of time, while Major Warne blows Caven and Dervish’s ship to pieces. As Hermack’s ship lands, Madeleine looks forward to a reunion with her father, but knows she will also be imprisoned for her part in the conspiracy; while the Doctor and his companions prepare to seek out the TARDIS on one of the fragments of the Beacon.

Series 6: The Seeds of Death

At the end of the twenty first century, a teleportation technology called "T-Mat" has replaced all traditional forms of transport, allowing people and objects to travel instantly anywhere on Earth. Manned space exploration has ceased due to the ease of life on Earth. The Second Doctor, Jamie McCrimmon and Zoe Herriot arrive in a museum on Earth run by Professor Daniel Eldred dedicated to the obsolete technology of rockets. However, something goes amiss at the T-Mat vital relay station on the Moon and the system breaks down. With communications out, and no way to reach the Moon without T-Mat, those responsible for the system, Commander Radnor and his assistant Gia Kelly, turn to Professor Eldred to help. He has been privately building a rocket in hopes of re-igniting interest in space travel. In the absence of a space program to provide trained astronauts, the Doctor and his companions volunteer to crew the rocket.

On the moon, the relay station has been subject to a takeover. Controller Osgood has been killed sabotaging the relay system to try and prevent a takeover, and his deputy Fewsham has been pressed into assisting the invaders. Of the other technicians, Phipps is scared but defiant of the invaders while Locke actively tries to contact Earth and explain the situation, for which he is killed. The invaders are revealed as Ice Warriors, a militant Martian race, have taken control of the moonbase as a staging point for an invasion of Earth. Fewsham repairs the T-Mat link on receive mode and Miss Kelly beams through. She is put to work on repairing the full T-Mat system.

When the Doctor and his companions arrive on the moon by rocket – after a rather bumpy ride - they discover the situation and make contact with Phipps, who has evaded the invaders and is hiding in the moonbase. The Doctor accidentally reveals himself to the Ice Warriors and their leader the Ice Lord, Commander Slaar. It becomes apparent that the Ice Warriors have a deadly plan: they have seeds, which they send to various parts of Earth using T-mat, of a fungus that will multiply and suck all the oxygen from the surrounding atmosphere, making it more comfortable for the Martians but uninhabitable for humans. Once the full T-Mat relay is repaired, one seed is sent to Earth Control and explodes, killing a technician called Brent and alerting Radnor and Eldred of the danger. The seed soon creates foam which multiplies its effects and imperils more and more people. Other T-Mat terminals across the world receive more seeds with similar effects. Radnor takes a while to work out that the seeds seem to have been deposited in a pattern – all in the Northern zone, where the country is facing winter. The Ice Warriors also use T-Mat to dispatch a small advance force to seize Earth's weather control systems in London and ensure good conditions for the growth of the fungus.

Back on the moon Miss Kelly and Phipps work with Zoe and Jamie to stage diversions and attacks against the Ice Warriors. During their main assault to free the Doctor, Phipps is killed. The Ice Warriors have now retreated to their spacecraft to plan the next stage of their invasion, leaving an opportunity for most of the captives to flee the moonbase. Fewsham, however, remains behind, seemingly fearing an enquiry into his actions if he returns to Earth.

The Doctor’s first action in T-Mat control on Earth is to deduce how to stop the seed pods exploding, and works out they can be defeated using water. This explains where the Ice Warrior beamed to Earth has gone, and the Doctor tracks him down to the weather control system, where the alien has been stationed to prevent any rain fall that would be deadly to the pods. The Doctor and his allies recaptures the weather control system and summon rain, destroying the fungus which is used to the dry conditions on Mars.

Fewsham has meanwhile delivered a crushing blow to the Ice Warriors. He dupes Slaar into revealing into a live link with Earth that the main Martian invasion force is following a homing signal to the Moon, for which he is killed. But at least the Doctor now knows the full extent of the Ice Warrior plans. He decides to return to the moonbase and set a new signal for the Martian fleet from there, but knows to do so will be very dangerous. The Doctor uses T-Mat to return to the Moon and confronts Slaar while cleverly substituting the alternative signal. This draws the Martian fleet away and lures it into the Sun. Slaar moves to kill the Doctor in revenge but the arrival of Jamie in a T-Mat cubicle causes chaos, and Slaar is killed in one of the sonic beams of the last of his warriors. Jamie then kills the surviving Martian and the invasion is over. The Doctor and Jamie return to Earth and then make their goodbyes before departing in the TARDIS with Zoe.

Series 6: The Krotons

On an unnamed planet, a race called the Gonds are subject to the mysterious Krotons, unseen beings to whom they provide their brightest intelligences as “companions”. Thara, son of the Gond leader Selris, is the only one of his race to object to this practice. The Second Doctor, Jamie and Zoe arrive in time to witness the death of one of the chosen companions and intervene to save Vana, the other selected for this fate, using her survival as a means to convince Selris and the Gonds of the malign influence of the Krotons on their society. The Doctor calls it "self-perpetuating slavery” by which the brightest in Gond society have been removed. Similarly, there are large gaps in their knowledge, especially relating to chemistry. This situation has been in existence for many years since the Krotons arrived in their spaceship, polluting the lands beyond the Gond city and killing much of the Gond population.
Thara uses the disquiet of the situation to lead a rebellion and attack the Teaching Machines of the Krotons in the Hall of Learning. This prompts a crystalline probe to appear and defend the Machines, and warned the Gonds to cease their rebellion. Zoe now tries the Teaching Machines and is selected to be a “companion” of the Krotons. The Doctor elects the same fate and both are summoned into the Dynotrope where they are subjected to a mental attack. . Zoe deduces that the Krotons have found a way to transfer mental power into pure energy, while the Doctor busies himself with taking chemical samples of the Kroton environment. Circumstances now trigger the creation of two Krotons from chemical vats with the Dynatrope (the Kroton spaceship). The newly created Krotons capture Jamie but are really seeking the Doctor and Zoe, the “High Brains”, who have now left the Dynatrope. It takes Jamie quite some time before he is able to make an effective escape.
Eelek and Axus, two councillors previously loyal to the Krotons, who begin to rally for all-out war with the Krotons, have now seized the initiative in Gond society. The more level headed Selris is deposed, but warns that an all-out attack will not benefit his people. Instead he has decided to attack the machine from underneath by destabilising its very foundation in the underhall. Eelek has Selris arrested and also reasserts control by negotiating with the Krotons that they will leave the planet if provided with the two “High Brains” who can help them power and pilot their ship. Zoe and the Doctor are forced into the Dynatrope and Selris dies providing them with a phial of acid which the Doctor adds to the Kroton vats. Outside, Jamie and the scientist Beta launch an attack on the structure of the ship using sulphuric acid. This two pronged assault destroys the tellurium-based Krotons and their craft. The Dynatrope dissolves away and the Gonds are free at last - choosing Thara rather than the cowardly and ambitious Eelek to lead them.

Series 6: The Invasion

After the newly reformed TARDIS evades a missile fired at it from the dark side of the moon, the Doctor, Jamie and Zoe arrive in late twentieth-century London. However the TARDIS's visual stabiliser has become damaged, rendering it invisible. In order to have it repaired, they set out to find Professor Travers (of The Abominable Snowmen and The Web of Fear) and ask for his assistance. When they arrive, they find that he has left for America, leaving his home in the care of Isobel Watkins and her scientist uncle, Professor Watkins. She explains that her uncle has disappeared, after he worked on an invention for International Electromatics. The Doctor and Jamie go to IE's head office in London to investigate.

When the computerised receptionist won't let them past, they seek out another point of entry; this leads them to being gassed and taken to see IE's Managing Director, Tobias Vaughn. He apologises for the rough treatment the companions have endured, and explains that Professor Watkins was engrossed in a delicate stage of his work and agreed to remain on site—a statement which has piqued the Doctor's suspicions. After they leave, Vaughn reveals an alien machine, by opening a hidden panel in the wall, which tells him that the Doctor and Jamie have been recognised from Planet 14 (see Notes, below), and are a threat to their plans.

The Doctor and Jamie are abducted by two men, Benton and Tracy, and taken to a military transport aircraft, housing a complete operations room, where they are met by the (now) Brigadier Lethbridge-Stewart. He explains about UNIT, and the taskforce's investigation of IE.

Concerned about their failure to return, Zoe and Isobel leave for IE in search for them. They also encounter the receptionist, and are similarly frustrated when Zoe's inquiries about the Doctor and Jamie are all but ignored. Instead of seeking another method of entry like Jamie and the Doctor, Zoe verbally inputs an unsolvable ALGOL equation that overloads and destroys the receptionist, which leads to their capture. Isobel is used to make her uncle, who is being held captive, co-operate.

The Doctor and Jamie return to Travers' house, to find a note from Zoe and Isobel, explaining their going to search for them. They return to IE, and find several packing cases being loaded onto a train—one of which has an item of Zoe's clothing showing. However, they are again captured by the security chief Packer (who captured them the first time around), and again taken to Vaughn, where the Doctor accuses him of kidnapping Zoe and Isobel (a claim he flatly denies). Vaughn invites the two companions to come to the company's country compound, where the train will be arriving; it is here where they meet Professor Watkins, who has been warned to not mention Zoe and Isobel's whereabouts. He shows the Doctor his cerebration mentor, a teaching device that is capable of inducing emotional changes.

The Doctor queries Vaughn of the deep space communicator he noticed when he came into the compound; in return, Vaughn demands that the Doctor explain about the failed visual stabiliser, even threatening to hand Zoe and Isobel over to Packer if he doesn't co-operate.

The Doctor and Jamie escape onto a railway siding. Whilst hiding in the crates, Jamie has a near encounter with an automated cocoon. They emerge from the crates, and overhear guards being ordered to take Zoe and Isobel to the tenth floor.

Vaughn confides in Packer that he intends to use the cerebration mentor to control the Cybermen once they have invaded Earth; he also intends to use the TARDIS as a "getaway car", should he fail.

Vaughn broadcasts over the intercom system to the Doctor that he has ten minutes to surrender or Zoe and Isobel will be harmed. The Doctor uses a radio transceiver (given to him by the Brigadier) to order in assistance from UNIT, who — with the use of a helicopter — assist in rescuing Zoe and Isobel from the room they are locked in. Realising how dangerous UNIT are to his plans, Vaughn exercises hypnotic control over Major General Rutlidge, and orders him to cease UNIT's investigations.

The Doctor examines photographs of UFOs over the IE factory, and reasons that those ships are bringing cocoons to Earth. He, along with Jamie, sneak into the London IE warehouse, where they witness the emergence of a Cyberman from its cocoon. They go and warn the Brigadier that a Cyberman army are invading Earth, and that they are hidden somewhere on Earth. (the Doctor later states that they are hidden in the sewers.) However, Rutlidge has ordered the Brigadier to cease all investigations against IE. Lethbridge-Stewart intends to gain authority from Geneva, but requires proof to back his reasoning. Isobel offers her expertise as a photographer, but the Brigadier refuses.

Vaughn tests Watkins' device on an awakened Cyberman; however, the alien is driven mad by the machine, and escapes into the sewers. Vaughn reveals that in an hour's time, the Earth will come under the control of the Cybermen through a micro-electronic circuit built into every IE device; the Doctor discovers this same circuit when he opens up an IE radio, and sets about making a device to block the telepathic signal.

Meanwhile, Isobel, Zoe and Jamie have ventured into the sewers to obtain proof of the Cybermen's presence on Earth, narrowly escaping them in the process. The photos, however, prove to be worthless as they look too much like fakes.

Watkins perfects his machine and delivers it to Vaughn, but discovers that the Managing Director has been partially cybernised. UNIT manage to free Watkins from IE, during which time the Doctor creates a neurister, which neutralises the Cybermens' hypnotic signals. The Brigadier orders all the troops to have one of these taped to the back of each one's neck. At dawn, the signal is broadcast, causing the collapse of the human race; leaving the Cybermen able to take over London.

UNIT plan to use a Russian rocket to destroy the source of Vaughn's signal, while using UK missiles to destroy the incoming Cyberfleet. Captain Turner is sent to Russia to organise the rocket, while the Brigadier goes to the Henlow Downs missile site. The Doctor stays back to try and dissuade Vaughn one last time. The missiles are successfully launched, with help from Zoe, and the Cybermen blame Vaughn for the setback in their plans, announcing that they will use a megatron bomb to destroy life on Earth. Furious, he uses the cerebration mentor to destroy the machine in his office.

The Doctor persuades Vaughn to now aid humanity instead of try to defeat it, and they take a helicopter to the factory, where they used Walkins' machine to battle the massed army of Cybermen; UNIT forces arrive later to assist. Vaughn is killed in the skirmish, but the homing signal is successfully shut down. The megatron bomb is destroyed by a missile, while the rocket destroys the last Cyberman ship, consequently stopping the hypnotic signal.

With the crisis now over, and the visual stabiliser circuits now repaired, the Doctor, Zoe and Jamie leave in the TARDIS.

Series 6: The Mind Robber

In defeating the Dominators on Dulkis, the Second Doctor sets off a volcanic eruption. He leaves the TARDIS, along with his companions, Jamie and Zoe, in the way, though, and it gets buried in lava, blowing a fluid link (The Daleks) in the process. This forces the Doctor to use the emergency unit to take the TARDIS away from danger and indeed out of reality itself.

They land in a white void and as the Doctor fixes the TARDIS, Jamie and Zoe are lured outside and are confronted by white robots. The Doctor gets them back inside but, as they try to return to reality, the TARDIS explodes and the travellers are scattered into nothingness.

They end up in a forest where the trees become letters when seen from above. The Doctor, after facing a series of riddles, finds Jamie, but accidentally changes his face. They are soon reunited with Zoe and then encounter Gulliver, who gives them away to life-sized toy soldiers. They are taken to the edge of the forest, where a unicorn charges at them. They manage to turn it into a statue by loudly declaring that ‘it doesn’t exist.’

They continue on and reach a house, where the Doctor brings Jamie back to normal. They discover that the house is the entrance to a labyrinth. Here, while leaving Jamie behind, the Doctor and Zoe encounter the Minotaur and Medusa, whom they deal with in the same way as the unicorn.

Jamie, pursued by a soldier, climbs up a rock face with the help of Rapunzel’s hair and enters a citadel through a window, triggering off an alarm. He hides and finds Gulliver, who cannot see the White Robots who are chasing Jamie.

The Doctor and Zoe exit the labyrinth and encounter the Karkus, a cartoon character from Zoe’s home era. The Doctor accidentally manages to dispel the Karkus' "anti-molecular ray disintegrator" by commenting that no such weapon exists, and the Karkus attacks them. Unfortunately the Doctor can't get rid of the Karkus, because he has never heard of the character before and cannot say for certain that the Karkus is not real. Zoe, however, beats the Karkus into submission with her martial arts skills, and he allies himself with them. He takes them to the citadel, where they find Jamie. Zoe accidentally sets off the alarm again, but the trio do not hide and instead let the robots take them to the main control room.

Here, they meet the Master, a kidnapped Earth writer who underwent the same tests as them when he first arrived. He explains that he is getting old and needs the Doctor to replace him as creative source for the Land of Fiction.

While he is talking, Jamie and Zoe sneak into a library area where they encounter the White Robots again and become trapped in a giant book. The Doctor refuses the Master’s offer and climbs out through a skylight.

The Master hypnotises Jamie and Zoe, gets them to trap the Doctor and links him up to the Master Brain. The two battle, summoning up various fictional characters to fight against one another. The Doctor prevails, releasing Jamie and Zoe who override the Master Brain, causing the White Robots to destroy each other.

The Doctor unplugs the Master from the Brain and they all retreat to a side room. The White Robots destroy the Master Brain, the TARDIS comes back together and normality is restored.

Series 6: The Dominators

An alien craft bearing the imperious and ruthless Dominators arrives on the peaceful planet of Dulkis. The senior, Navigator Rago, is at odds with Probationer Toba, making for an uneasy partnership. The craft lands on the Island of Death, a nuclear test site that now houses an anti-war museum, and soon absorbs all the radiation on the island. The robotic Quarks are then sent out by the Dominators to prepare bore holes into the planet’s crust, since the Dominators wish to convert the planet into rocket fuel. Toba uses the Quarks to fire on and kill three indolent, rich adventure seekers who stumble across his project. Their pilot Cully, however, survives by hiding himself away, though the craft that brought him to the island is destroyed. Rago is furious that these potential slaves have just been wasted.

The TARDIS has arrived on another part of the island and the Second Doctor and his companions Jamie and Zoe begin to look around. The Doctor has been to Dulkis before and is looking forward to a good holiday when they hear the explosion of the craft being destroyed. They take shelter in the museum building where they meet three other newly arrived Dulcians, Educator Balan and his young charges Teel and Kando. All are puzzled that the radiation reading on the Island reads nil, since it should be radioactive after the nuclear explosion 172 years earlier, and since that time the Dulcian civilisation has rejected all weapons. Cully arrives too, and tells them about the murderous Dominators and their robots. Balan does not accept this: he knows the son of the Director of the ruling council is well known as a con artist.

The Quarks have meanwhile marked out their drill sites, and begin work on drilling the outer bore holes. However, their power supply seems limited, and Rago is very keen to conserve their energy supplies to vital activities only. This actually saves the Doctor and Jamie when they are captured by a patrol of Quarks rather than killed, and taken to the Dominator ship for questioning and scanning. A scan of Jamie is presumed to apply to them both and to the Dulcian race as a whole, who are thus described as possible but not definite for conversion into a slave force. When it is time for an intelligence test the Doctor feigns stupidity to prove their worthlessness. He also fails to use a weapon from the Dulcian museum, falsely claiming such advanced technology has been lost to the Dulcians. The Doctor and Jamie are freed as worthless idiots.

Cully has contacted his father, Director Senex, who orders him to recharge Balan’s travel capsule and use it to return to the Capital City. He takes Zoe with him on the journey to the Council Chamber, where the discussion lacks focus and purpose. Senex refuses to believe that Cully is telling the truth, despite Zoe’s protests, so Cully steals a travel pod and heads back to the island with Zoe to get proof of their story. At the same time the Doctor and Jamie take Balan’s pod to the Capitol City. They are angry that Cully and Zoe have been allowed to return to danger and have real trouble convincing the Council of the threat which the Dominators pose, with the Dulcians repeatedly demonstrating a totally pacifist stance. The true danger is only revealed when the Council obtains a visual image of the survey station near the museum which the Quarks destroyed on Toba’s instructions – another case of wasted power in the eyes of an increasingly exasperated Rago.

The Dominators have meanwhile captured Balan, Teel and Kando, using them for further tests on their species, which the Dominators assume are a higher life-form than the Doctor. They are assigned to work as slaves in the drilling sites under the supervision of the Quarks. Zoe and Cully are soon captured too and added to the slave force, but find Balan and Kando totally opposed to using force against the overseeing Quarks. Over time, however, they all start to falter under the weight of the burden of digging the bore hole, with Balan collapsing first. Cully manages to sneak away back to the museum and capture a laser weapon stored there as an exhibit.

The Doctor and Jamie have meanwhile taken control of a travel pod and steer it back to the Island of Death. Jamie links up with Cully at the museum while the Doctor is captured by Quarks and taken with the slave force back to the Dominator ship. Cully uses the gun to destroy a Quark, prompting another of Toba’s rages. The museum is destroyed in retaliation, which once more enfuriates Rago. He orders the Quarks to hold the Doctor and Zoe for further tests while Balan, Kando, and Teel are sent to excavate to the central bore site.

Jamie and Cully survived the explosion in the museum and are hiding in a nuclear bunker below the main building. After a struggle they succeed in opening the hatch above them. They survey the area and succeed in crushing a Quark with a boulder. An angry Toba is alerted via an alarm on the ship and heads off to investigate how another Quark has been destroyed, leaving the Doctor and Zoe free to roam the Dominator ship and work out more about its power source. Jamie and Cully remain free and use the opportunity to attack other Quarks in a series of guerrilla raids.

The Dulcian Council debates the situation and not even Tensa, Chairman of the Emergencies Committee, can spur them into decisive action. The key moment comes when Rago himself uses the travel pod appropriated by the Doctor to travel to the Capitol with a Quark. The robot kills Tensa on command. Rago says that the fittest Dulcians will now all be converted into a slave force to use on the Dominator homeworld, with the Quarks used there redeployed to the front line of their expanding empire. Those not selected will be left on Dulkis to die, as the planet is doomed. Having finished his ultimatum, Rago stalks away.

Toba now returns to the ship, with his slaves in tow, and demands to know who destroyed the Quark. Balan is killed for refusing to answer, and the Doctor is selected to die next. Luckily for him Rago returns and is incensed that Toba has wasted more lives and not even begun work on digging the central bore hole even if the four perimeter ones have been completed. Toba is sent to complete the drilling and prepare the bore rockets, using the Quarks and the Doctor, Zoe, Teel and Kando as slaves; while Rago focuses on a precious seed device that is intended to be dropped down the central bore hole. Rago also hears from the Fleet Leader that no Dulcian slave force is to be assembled: all the Dulcians are now to stay on the planet to die when it is destroyed.

The dig proceeds with the Doctor and the other slaves making some progress, but when Toba abandons his watch post Jamie and Cully seize their opportunity and disable another Quark to enable the freedom of their friends. The Doctor has now worked out the Dominator scheme: a nuclear fission seed will be dropped down the bore hole which will convert the entire planet into a radioactive mass ideal for use in powering the Dominator fleet. The four outer bores are for launching rockets through the planet’s crust – which is especially thin at the point of the Island – and will cause volcanoes to erupt; while the seed will then be used to detonate the volcanoes being created and begin a radioactive chain-reaction. Their collective response is to capture the seed and they begin digging a perpendicular tunnel which should reach the central bore hole and enable them to steal the deadly device before it can detonate. However, there is little that can be done to stop the volcano creation. Jamie and Cully support this effort by continuing to attack and destroy Quarks with homemade bombs. This has the desired effect of totally fracturing the relationship between Rago and Toba, as they argue about priorities rather than prioritising the dig, but yet the bore hole is still ultimately completed and the seed primed.

The access tunnel scheme is successful and the Doctor intercepts the seed during its descent, telling his friends that it cannot be defused. Cully, Teel and Kando are told to flee in the remaining travel pod, while Jamie and Zoe are sent to the TARDIS to wait. The Doctor will deal with the seed himself. He tears off to the Dominator ship and manages to smuggle the seed on board before the craft lifts off. It soon departs and the Dominators’ last vision is of the seed device rolling on the floor toward them. The Doctor watches the Dominator ship being destroyed and then heads back to the TARDIS where he and his two companions must depart in a hurry to avoid the advancing lava flows from the new volcanoes...
