SCIENCE-FICTION’S MOST ASTOUNDING STORY!
An evil alien brain, bent on world dominance, takes over the body of an atomic scientist, while a “good” alien brain inhabits the body of the scientist’s dog and waits for an opportunity to defeat the evil brain.
A solid B-movie from the man who made The 7th Voyage of Sinbad, Attack of the 50 Foot Woman and The Deadly Mantis (Nathan. H. Juran).
