The Time Warrior (airdate May 17, 1987)
Intro: The Doctor discovers a charming stowaway, who will find a new career. And we will learn for the first time the name of the Time Lords' home planet. There'll also be a contretempsbetween a Sontaran captain and a medieval robber baron. Should be an interesting evening.
"Next Week": Prehistoric monsters suddenly appear in London. It's the "Invasion of the Dinosaurs," and you can bear witness next Sunday evening at 11.
