When a magician named The Great Sadini emerges from his trailer one night, he notices a young man named Hugo lying unconscious on the carnival grounds and takes him to his trailer. The boy is a runaway from a "home" who proves to be simple-minded; his first impression upon waking is that Sadini and his wife are the devil and an angel respectively. Sadini's compassionate nature compels him to take the kid under his wing and teach him about magic. Conversely, the cold-hearted wife has something more sinister in mind and implores the impressionable young man to commit a murder.
