The films opens with a trio of grave robbers (led by a man named Lynch) delivering a corpse to Baron Frankenstein (Cotten) and his assistant Dr. Marshall (Müller), for obvious reanimation purposes. Baron Frankenstein's daughter Tania (Neri/Bay) arrives from school, having completed her studies in medicine, and is greeted by her father and his servant, the handsome but mildly retarded Thomas. Tania reveals to her father that she has always understood his work with "animal transplants" to be a cover for his work reanimating corpses, and that she intends to follow in his footsteps and help him in his work.
