Frankenstein Must Be Destroyed

Baron Frankenstein is once again working with illegal medical experiments - brain transplants to keep the most brilliant minds working in new bodies. He has just finished decapitating a physician for his work when a burglar, fleeing a patrolling officer, accidentally lets himself into the baron's lab. The robber is horrified to see the head and flees to tell the police. Frankenstein knows this location is no longer viable and changes to a new city. He forces a young doctor, Karl, and his fiancee Anna to assist him after he catches Karl smuggling drugs from the mental institution where he works for Anna's ailing mother. First, the baron wishes to rescue his fellow researcher, Dr. Brant, who is a patient at the mental institution. He is desperate to learn Brant's secret about preserving brains. Brant is nabbed but is in bad physical shape having suffered a heart attack. He needs a new body immediately. So, the baron eliminates the asylum director, Professor Richter, whose body he can utilize. A nosy police inspector starts to put clues together about missing medical equipment and people who have vanished. His officers nearly stumble on Frankenstein's lab but miss it. When Brant awakes by himself in his new body, he is not thrilled. Neither is his wife when he calls on her. She had already seen his original body in a hidden grave.
