The Doctor, Ian, and Barbara land on Dido...not the singer, don’t worry, she’s fine...only to be instantly separated after discovering a crashed rocket ship on the planet’s surface. But a slightly menacing figure named Koquillion is keeping crash survivors Vicki and Bennett confined to the rocket. The Doctor, however, having been to Dido before, finds things aren’t as they ought to be. Can he uncover the rather delightful twist at the end of the story? Can Barbara manage to not point the flare gun at herself? And can we get a moment of silence for Sandy? It’s time for The Rescue! Oh! And today just happens to be Maureen O'Brien's birthday! How's that for timing?
