Intro: How do you deal with a sentient being with great power who has lived for thousands of years in a black hole in an anti-matter universe and wants out, and will destroy the universe if it doesn't succeed? Would you send for The Kingston Trio? Curly, Larry and Moe? Or "The Three Doctors"

Outro: Now that they are free to travel in time and space again, The Doctor will propose a trip to the famous blue planet Metebelis Three for a little rest and recreation. Tune in to see if they need a new travel agent next Sunday night at 11 when The Doctor and Jo become captivated, or is it captured, by the "Carnival of Monsters." [source: ChicagoEpguides]
