The Doctor has adopted many guises in his time, but to be hailed as the great god Zeus is a bit of a shock. Yet this is exactly what happens when the TARDIS lands on the plains of Asia Minor, not far from the city of Troy. Taken to the Greek camp by Achilles, the Doctor is introduced to Agamemnon and Odysseus and forced to admit his less than godlike status. He is then given just two days to come up with a strategy for defeating the Trojans... Meanwhile, Steven and Vicki have been taken prisoner by the other side. The Trojans are convinced that Vicki is a spy - and to prove her loyalty she must concoct a plan to defeat the Greeks! Like the Doctor, she has just two days to do it. Luckily for the Doctor, a certain someone has already devised a scheme for beating the Trojans. Even if the wooden horse was invented for a piece of fiction written in the eighth century, it still works... As the opposing forces come face to face in a climatic battle, there are dangers aplenty for both Steven and Vicki. By the time the TARDIS moves away again, it will have both lost and gained a crew member.
