A podlike spacecraft is on an intercept course for Earth, and nervous humans' first instinct is to shoot first and ask questions later. Instead, they discover a race of golden, beautiful aliens asking for help and offering an unlimited source of energy--with a catch. Originally this 1971 adventure was to be called "The Vampire from Space," but that was too obvious, particularly when the villainous Master (Roger Delgado) is really behind this latest threat to Earth. Can the Doctor (Jon Pertwee) discover the awful truth about Axos in time, or will his desire to free himself from the planet overcome his better judgment?
