Doctor Who vs. his oldest and deadliest enemy.
Doctor Who (Jon Pertwee) is forced into not one but three desperate races against time. One, an unexplained power loss has stranded the TARDIS on a sinister planet called Exxilon. Two, he must help an expedition from Earth find a rare mineral that can cure a space plague that threatens all human life in the galaxy. Three, he must save his colleague Sarah, who has been captured by the savage Exxilons, from becoming a human sacrifice. To locate the source of the power drain, help the Earth expedition and save Sarah, the Doctor plots to uncover the secrets of the ancient Exxilon city. But his plans are threatened by new arrivals on the planet — The Doctor's oldest and deadliest enemies — the Daleks!
