Twenty years ago, a little accident with a guillotine trick left magician Duke Duquesne's wife and on-stage assistant without a head... and their baby daughter Cassie without a mother. Now The Great Duquesne may have another trick up his sleeve. He dies, leaving Cassie a sizeable inheritance if she'll spend seven nights in his spooky mansion. With a fearless young reporter at her side, Cassie braves terrors that could be the work of evil spirits. Or are they illusions dreamed up by Cassie's dear, demented dad? Connie Stevens, Dean Jones (in his pre-The Love Bug days) and Cesar Romero star in a creepy horrorfest that offers fans scares, screams, a return of that guillotine and Max (Gone with the Wind) Steiner's penultimate score.
