A group of sexy space vixens flies down to Earth, sets up a shop at a carnival (disguising their ship as a ride), and kidnap some earthlings in their scheme to conquer our planet. The humans, including Marcos, a crooked boxer and our hero, Silvia, his love interest, and a gang of comical mobsters out to kill Marcos, are taken to the women’s home planet. There they are held prisoner by the evil queen Adastrea and aided by her selfless twin Alburnia. Meanwhile, a standard issue hunky scientist back on Earth, who happens to be Silvia’s boss, tries to rescue them.
An U.S. Spaceship lands on a desolate planet, stranding astronaut Taylor in a world dominated by apes, 2000 years into the future, who use a primitive race of humans for experimentation and sport. Soon Taylor finds himself among the hunted, his life in the hands of a benevolent chimpanzee scientist.
