When an atomic war on Mars destroys the planet's women, it's up to Martian Princess Marcuzan and her right-hand man Dr. Nadir to travel to earth and kidnap women for new breeding stock. Landing in Puerto Rico, they shoot down a NASA space capsule manned by an android. With his electronic brain damaged, the android terrorizes the island while the Martians raid beaches and pool parties
