A scientist, Professor Jakob ten Brinken, interested in the laws of heredity, impregnates a prostitute in a laboratory with the semen of a hanged murderer. The prostitute conceives a female child who has no concept of love, whom the professor adopts. The girl, Alraune, suffers from obsessive sexuality and perverse relationships throughout her life. She learns of her unnatural origins and she avenges herself against the professor.
