Baron Ivan Rassimov, a brilliant doctor, died horribly during a fire burst in his laboratory. Since that day, his daughter Tanja retired to a life of reclusion, covering with a dark veil her disfigured face. Professor Nijinski was once a student of Rassimov; he married Tanja, and he's trying to restore her lost beauty with a series of skin transplants. However, to reach his goal, professor Nijinski needs beautiful young victims for his transplant experiments.

Ali Baba's powerful uncle hates how his nephew visits many beds of the caliphate and fetches a professor to set Ali Baba on the straight-and-narrow, but Ali humiliates the professor. Thinking Ali Baba is gay, Qadi's wife sets up a wedding, enlisting the help of a sorceress's magic potion to make Ali Baba fall for the selected woman, but the bride-to-be falls for Ali Baba instead.

Anijeska, the Rassimov's heir, moves with her husband, Dr. Alex Nijinski, to her father's mansion. In the basement, the doctor discovers the laboratory in which the late Rassimov carried out horrifying experiments.
