A Group of space men from the planet Krankor who resemble chickens are led by their leader, Phantom to invade Earth. But a strange superhero named Prince of Space (actually a bootblack in disguise) arrives to defeat the spacemen. Although the weapons of the aliens cannot harm the Prince of Space, the Phantom continues to fight, and many plot twists (including capturing a group of elderly scientists) ensue.
