Castrovalva

(Series 19, Episodes 1-4)

Summary: Problems with his regeneration mean the Doctor has to hang out in the Zero Room whilst the Master uses Adric as a stooge to programme the TARDIS controls to fly them into the Big Bang.  Adric’s caught in the Master’s web, luring the Doctor to Castrovalva - the only place where he can sort out his regeneration complications – where Tegan and Nyssa set out with the Doctor in the Zero cabinet in very unsuitable shoes.  Everyone becomes trapped in a splintering universe and a suspicious librarian saves the day.

Watch it because: I’ve got a feeling it’s going to be absolutely splendid.
