Frankenstein Meets The Space Monster

An atomic war on Mars has killed or mutated all the women and most men on the planet. Martian Princess Marcuzan, her advisor Dr. Nadir, and the remaining normal men to travel to Earth. They hope to capture some young Earth women for breeding stock. As they approach our world, they mistake a NASA rocket launch for Mars as a missile attack and shoot it down. The entire Martian contingent plus Colonel Frank Saunders, the android astronaut aboard the jettisoned space capsule, land in Puerto Rico. The Martians fear that their mission is in danger if the android reports back about seeing them. Princess Marcuzan sends a patrolman to shoot him. The crewman's ray gun melts half his face but does not kill him. With his electronic brain damaged, the android begins terrorizing the island based on the program in his self-protection unit. Meanwhile, the Martians raid beaches and pool parties for young women. They soon have nine candidate women held their craft, where they put the through a purification process. Dr. Adam Steele, Frank's creator, tracks down the misbehaving android and gets him under control. He sends his assistant, Karen Grant, to notify the military officials of their location. But the Martians capture her as she makes a run for help on a motor scooter. She, too, is taken to the ship. Nadir recognizes her tracking unit as something important and interrogates her. When she will not comply, he orders her restrained in the cage next to Mull, a mutant Martian they brought to handle any interference with their mission. Adam and Frank stumble on the craft. Frank is able to release the Earth women plus Karen. He then takes on Mull.
