Plot
An outer space terrorist from a planet named Arous, a brain-shaped creature named Gor (Dale Tate), arrives on Earth and possesses young scientist Steve March (Agar). Gor proceeds to use his vast, destructive powers to bend the world to his will, threatening to wipe out the capital city of any nation that dares to defy him.
Meanwhile, Vol (Tate), another brain creature from Arous, arrives and eventually inhabits the body of March's fiancee's dog. Vol goes on to explain that Gor is a wanted criminal on their world. His only physical weakness is the human body's fissure of Rolando, and Gor is only vulnerable during the brief period when he needs to exit his host to absorb oxygen.
