With the Tardis wrecked by the Time Lord's regeneration, he crash-lands in a quiet English village, where he finds himself in need of a new companion. Perfectly placed for the job is Amy Pond, who joins him to help fend off the Atraxi, thuggish galactic policemen who have appeared through a crack in her bedroom wall in pursuit of a mysterious criminal. Karen Gillan stars as Amy, with guest appearances by Nina Wadia (EastEnders' Zainab) and Annette Crosbie (One Foot in the Grave), in the first episode under the control of new lead writer Steven Moffat.
