Louis Cyphre hires private investigator Harry Angel to find missing singer Johnny. At the hospital, Angel learns that the singer has disappeared. It is no ordinary missing-person’s case. Everyone he questions dies soon after, as Angel’s investigation ensnares him in a bizarre tangle of black magic, carnival freaks, and grisly voodoo. When the sinister Louis Cyphre begins appearing in Angel’s dreams, the detective fears for his life, his sanity, and his soul.
