Thrown off course by a howling storm, [[the Doctor's TARDIS|the TARDIS]] lands in a bleak, desolate stretch of countryside. The [[Eleventh Doctor|Doctor]] [[deduce]]s that it has arrived in [[Hampshire]] in the [[1920]]s and, sniffing the air, he smells a distinct odour of sulphur — indicating that a spaceship has crashed in the area. While [[Rory Williams|Rory]] goes to fetch an umbrella, [[Amy Pond|Amy]] and the Doctor brave the rain to find the stricken craft. It is huge, shiny, silvery-blue — and completely empty. A set of footprints leads to a cosy-looking, old-fashioned cottage: but the house, too, is deserted. However, the Doctor and Amy can distinctly hear people talking — and one of the voices sounds like Rory's. How could he be in the cottage when he was last seen heading back to the TARDIS? Where are the residents of the empty house? And what has happened to the inhabitants of the spaceship?
