When Erich von Stroheim was unable to work directing, he took work acting and turned in some very solid performances. This is one of them. In this movie, he portrays a mad magician who is insanely jealous and devises a plot to hypnotize his wife/assistant into killing the man he suspects to be her lover. A classic case of paranoia and backfiring plots, this movie is otherwise uninteresting and the acting other than von Stroheim's is uninspired.
