Horror drama starring Andrews as a mad scientist determined to bring dozens of frozen Nazis back to life after he has kept them in a meat locker (in uniform) since the end of WW II. He succeeds in making the Germans ambulatory, but he can't get their brains to work. To remedy this, his colleague snips the head off a female friend of Andrew's niece. They attach the head to a complicated apparatus in the hopes that her telepathic powers will aid them in their experiments.

At the end of World War II, 1,500 of Hitler's top officials were frozen alive and hidden in caves. Former Nazis Dr. Norberg and his aide, Karl Essen, are conducting revivification experiments at a manor in the English countryside. Although they have been successful in restoring body functions, they have been unable to revive the brain. They explain to visiting ex-Wehrmacht officer General Lubeck that they need a live brain with which to experiment. Consequently, when Norberg's niece, Jean, arrives from the United States with her college friend Elsa, the sadistic Essen disposes of Elsa but keeps her decapitated head alive in a laboratory cabinet. Although Jean is told that her friend had to leave suddenly for London, the young girl is unconvinced and reveals her suspicions to Ted Roberts, an American scientist. Roberts is permitted by Norbert to view the severed head, and he agrees to keep the secret. Meanwhile, Elsa's brain is developing a telepathic rapport with Jean in order to warn her that her life is in danger. After Lubeck has concluded that Essen is a security risk and ordered him put into the deep-freeze chamber, Jean sneaks into the laboratory and discovers Elsa's head. When Lubeck aims a gun at her, Norberg intervenes on behalf of his niece. As they engage in a death struggle, Elsa's brain activates a collection of electronically-controlled dismembered arms which reach out and strangle the two ex-Nazis.
