In the fictional European country of Amalia, the political interests of the British, American and Communist espionage communities are explored. Eschewing the action formula of its ITV contemporaries, the series dealt more politically oriented plots such as defections to the west, awakening "sleeper" agents and the leaking of official secrets.

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 god Zeus 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.
