The Edge of Destruction

The Edge of Destruction (also referred to as Inside the Spaceship) is the third serial in the British science fiction television series Doctor Who, which was first broadcast in two weekly parts on 8 February and 15 February 1964. The serial is distinguished as a rare "bottle episode", in that the entire story is shot on a single set, with just the main cast. It also serves to resolve several character threads that had been presented over the previous eleven weeks.
