Intro: The Doctor and friends will be in double jeopardy tonight, first from perhaps the most horrific malaise ever visited upon mankind: the plague. And second, from a horrendous race of alien monsters which are too awful to be described. How will our friends manage this dilemma? With just a touch of panic, a modicum of concern, a smidgeon of ingenuity, and an ample amount of aplomb as we will see anon, right here on WTTW, Chicago.

Outro: [Of] all the places in the universe, where do you suppose The Doctor and Nyssa will travel next week? Wrong, they're going to stay right in old Blighty, but move up several centuries in time to 1925. When we have moved up one week in time, you'll be able to see "Black Orchid."
