John Harley Duquesne, a psychotic stage magician, accidentally beheads his wife Melinda with a guillotine during a performance. Twenty years later he dies, and his will requires his daughter Cassie (the image of her mother) to spend seven nights in his apparently haunted mansion in order to inherit his estate.
Reporter Val Henderson offers to stay with her when he learns Duquesne promised to return in spirit form during Cassie's week-long vigil. As the days pass, the two encounter a number of spooky happenings, leading to a climax in which the very-much-alive Duquesne attempts a recreation of his guillotine trick, this time with his daughter as an unwilling assistant.
Henderson fights Duquesne, trying to prevent him from activating the guillotine, but accidentally releases the catch; a dummy's head falls from the guillotine causing Duquesne to break down thinking his wife has been killed. Henderson rescues Cassie as the police come to arrest Duquesne.
