Doctor Who Series 31: The Lodger

The TARDIS lands in Colchester rather than the intended destination of the Fifth Moon of Sinda Callista, and the Doctor steps out on to the grass. The TARDIS immediately takes off, unplanned, separating him and Amy. Meanwhile, passers-by are seen being lured into a nearby house by a voice seeking help, from the intercom at its front door. The door opens and they ascend the staircase to the first floor, entering the room which lies there; flashing lights are seen and screams heard emanating from the room.

The Doctor concludes that whatever happened to the TARDIS is connected to that room. Luckily, the owner of the downstairs flat, Craig Owens, is looking for someone to rent his spare room. The Doctor shows up and pays him with a bag containing £3000 (since he didn't know whether it would be too much). Though Craig finds him odd, he manages to convince him with his cooking. The Doctor eventually meets Sophie, a friend of Craig whom the latter cannot admit he's in love with.
