In this tongue-in-cheek movie inspired by Poe's poem, Dr. Craven is the son of a great sorcerer (now dead) who was once himself quite skilled at that profession, but has since abandoned it. One evening, a cowardly fool of a magician named Bedlo comes to Craven for help- the evil Scarabus has turned him into a raven and he needs someone to change him back. He also tells the reluctant wizard that Craven's long-lost wife Lenore, whom he loved greatly and thought dead, is living with the despised Scarabus.

In prison and awaiting execution, Dr. Victor Frankenstein recounts to a priest what led him to his current circumstance. He inherited his family's wealth after the death of his mother when he was still only a young man. He hired Paul Krempe as his tutor and he immediately developed an interest in medical science. After several years, he and Krempe became equals and he developed an interest in the origins and nature of life. After successfully re-animating a dead dog, Victor sets about constructing a man using body parts he acquires for the purpose including the hands of a pianist and the brain of a renowned scholar. As Frankenstein's excesses continue to grow, Krempe is not only repulsed by what his friend has done but is concerned for the safety of the beautiful Elizabeth, Victor's cousin and fiancée who has come to live with them. His experiments lead to tragedy and his eventual demise.
