Plot

In a village of the Bavarian Alps, Henry Frankenstein and his assistant Fritz, a hunchback, piece together a human body. Some of the parts are from freshly buried bodies, and some from the bodies of recently hanged criminals. In a laboratory he's built inside a watchtower, Henry desires to create a human, giving this body life through electrical devices. He still needs a brain for his creation. At a nearby school, Henry's former teacher Dr. Waldman shows his class the brain of an average human being and the corrupted brain of a criminal for comparison. Henry sends Fritz to steal the healthy brain from Waldman's class. Fritz accidentally damages it, and so brings Henry the corrupt brain.
