When meteors fall in a curious V-formation and crash on a field in England, an alien force possesses several scientists and infects bystanders with a deadly disease. Shielded from the meteor's influence by a metal plate in his head, Dr. Curtis Temple (Robert Hutton) discovers that an alien race on the moon seeks to use the manipulated scientists for secret purposes. But, as Temple learns more about the invaders, he realizes that they may not be as evil as he thought.
