The TARDIS arrives on Earth in July, 1966, on a runway at Gatwick Airport. Polly witnesses a murder in a nearby hangar and is then kidnapped by the perpetrator, Spencer of Chameleon Tours. Ben also vanishes. The Second Doctor and Jamie are left to convince the sceptical airport Commandant there has been foul play.
