Intro: Can The Doctor rescue Jo from the primitives? Can he deal with The Guardian? Can he cope with The Master? Can he contain the doomsday machine? The answers to these profound and disturbing questions will be forthcoming in the conclusion of "Colony in Space."

Outro: Next week, as we promised several fortnights ago, Sylvester McCoy returns as The Doctor. Be with us next Sunday night at 11 for "Remembrance of the Daleks." [source: ChicagoEpguides]
