Intro: Tonight, The Watcher appears. The Master threatens. The City of Logic begins to unravel. And The Doctor takes extreme action. You will be witness to it all as you travel with us now to "Logopolis."

Outro: Next week, the era of the Fifth Doctor begins with a regeneration of profound disorientation. Be with us next Sunday evening at 11 for "Castrovalva." [source: ChicagoEpguides]
