After atomic scientist Dr. Karl Noymann (John Carradine) dies in a lab accident, a strange thing happens: he shows up, alive, on the doorstep of his colleague Dr. Penner (Philip Tonge). Noymann explains to Penner that he’s actually an invisible alien possessing Noymann’s body, and he’s here to deliver a warning: if Earth doesn’t stop developing nuclear weapons, his moon-based race will possess the bodies of our dead and make war on Earth. Penner delivers the message, but he’s laughed at, at least until the aliens possess a plane crash victim and pilot him to the announcers booth at a hockey game, where he again delivers the Earth an ultimatum. International authorities decide to fight back, and the invaders make good on their threats, using the bodies of the dead to commit acts of sabotage and destruction. In response Earth gathers its top scientists in secure locations to try to find a way to defeat the aliens. Air Force Major Bruce Jay (John Agar) escorts Penner, his daughter (Jean Byron), and her fiancé, Dr. John Lamont (Robert Hutton) to a bunker designed to survive a nuclear war. Can anyone find a way to stop the Invisible Invaders? ![]()
