Intro: Tonight, 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 Lord's home planet. There'll also be a contretemps between a Sontaran captain and an medieval robber baron. Should be an interesting evening.

Outro: Prehistoric monsters suddenly appear in London. It's the "Invasion of the Dinosaurs" and you can bear witness next Sunday evening at 11. [source: ChicagoEpguides]
