Missing episode -animated recreation released by BBC.

The Doctor, Vicki and Steven arrive on an arid planet where they meet the beautiful Drahvins and the hideous Rills. Each has crash-landed after a confrontation in space. The Rills are friendly, compassionate explorers. The Drahvins are dull-witted, cloned soldiers, terrorised by the intelligent, warlike matriarch Maaga.

Both ships are damaged. The Drahvins' craft is irreparable, but the Rills' is almost ready to take off. Although unable to breathe the oxygen atmosphere, they employ efficient robot drones, which Vicki nicknames "Chumblies". Despite numerous offers by the Rills to take Maaga and her crew to safety, she refuses their aid. When the planet is discovered to be on the point of disintegration, Maaga tries to force the time travellers to help her steal the Rills' ship and kill the Rills. Instead, the Doctor allows the Rills to draw power from the TARDIS to refuel and escape, leaving the Drahvins to their fate.

When the TARDIS arrives on the plains of Asia Minor not far from the besieged city of Troy, the Doctor is hailed by Achilles as the mighty godZeus and taken to the Greek camp. He meets Agamemnon and Odysseus. Forced to admit he is a mere mortal — albeit a traveller in space and time — he is given two days to devise a scheme to capture Troy.

Steven and Vicki, meanwhile, have been taken prisoner by the Trojans. Vicki, believed to possess supernatural powers, is given two days to banish the Greeks to prove she is not a spy.
