Peter Davison's final adventure, "The Caves of Androzani," pulls out all stops to give this Doctor an unforgettable farewell. Deep within the titular caves, the disfigured, masked antihero Sharez Jek (Christopher Gable) and his regiment of androids are locked in conflict with an army unit and a group of smugglers for control of the life-extending Spectrox. When the Doctor and Peri (Nicola Bryant) enter this labyrinth, they immediately become victims of deadly Spectrox poisoning. The story's numerous subplots involve espionage, betrayal, and revenge, as well as big-business corruption, political assassination, and silly-looking reptilian monsters. And the first episode has one of the best cliffhangers ever: our heroes are executed by a firing squad armed with submachine guns.

Robert Holmes (who wrote the more satirical Doctor Who story "The Sun Makers") here concentrates on delivering a breathlessly paced action thriller, with relentless death and destruction unfolding like in a Sam Peckinpah film, making Davison's heroic pacifism all the more effective. --Gary S. Dalkin
