The TARDIS lands in what looks like an ordinary hotel, as the time-travelling drama continues. But the walls move, corridors twist and rooms vanish. There is a room for every visitor that contains their deepest, darkest fears. Fears that will kill them. What lies in the Doctor's room? And when his turn comes, will he welcome death like all the rest?
The episode was written by Toby Whithouse and guest stars David Walliam as Gibbis.
