Hugo is a retarded boy without a home. He is taken in by a kind, carnival magician, named Sadini. Sadini's deceitful wife, Irene, performs in her husband's act as the woman whose body is supposedly sawed in half. Irene manipulates Hugo into killing her husband. She says she wants to start a new act with Hugo and convinces him that he can perform the sawing-the-woman-in-half trick, because the magic is in the wand. Hugo kills Sadini for her, but then she backs out on her promise. Hugo accidentally knocks out Irene in a struggle. He then decides to attempt the trick since he has possession of the "powerful magic wand" and ends up sawing Irene in half for real.
