Tradition is important to the Great Zandini, the great magician of Paris. His grandfather was a magician, his father was a magician, and his son will be a magician too. Unfortunately, his son Theodore does not feel the same way. Zandini wonít hear of opposition. Besides, his arch nemesis, newspaper reporter A. S. Besette, has begun a smear campaign, suggesting the old master is washed up. Zandini creates a new magic show to introduce Theodore as his successor. Thereís only one problem: Theodore is a hopeless magician.Fortunately, his sister Fanny is a very good magician. Itís up to her to save the day, even if the Great Zandini does not wanther help.
