Trapped crew find a sinister locked door

The Doctor and his companions advance through the silent, corpse-strewn corridors of the Ark, arriving at a door marked Q section that refuses to open. The Doctor uses a screwdriver to probe the locked mechanism while explaining how they have arrived in an earlier era of the station’s timeline. Tension mounts as the party realizes they are cut off from the TARDIS and possible escape, their route blocked by something beyond the door which has already killed the crew. A metallic creature scuttling across the walkway underscores the Ark’s infection and shifts the story from arrival to desperate confrontation. key_dialogue: [ DOCTOR: Those poor fellows couldn't.
