Alraune, later renamed Unnatural: The Fruit of Evil, is a 1952 West German horror science fiction film, directed by Arthur Maria Rabenalt and starring Hildegard Knef and Erich von Stroheim. The film is based on the 1911 novel Alraune by German novelist Hanns Heinz Ewers. The plot involves a scientist (von Stroheim) who creates a woman (Knef) who is beautiful yet soulless, lacking any sense of morality.

Plot

Professor Jacob ten Brinken (Erich von Stroheim) loses his university teaching role due to his abnormal interest in studying artificial insemination. He was able to artificially impregnate a female prostitute with the sperm of a male murderer condemned to death by hanging. He raises the child, named Alraune (Hildegard Knef), the German word for mandrake root, which has a variety of connotations in German folklore for its seemingly human-shaped appearance as well as its hallucinogenic effects.
