The Amazing Arden is the most famous female illusionist of her day, renowned for her notorious trick of sawing a man in half on stage. One night in Waterloo, Iowa, with young policeman Virgil Holt watching from the audience, she swaps her trademark saw for a fire ax. Is it a new version of the illusion, or an all-too-real murder? When Arden's husband is found lifeless beneath the stage later that night, the answer seems clear, and she has only one night to convince a small-town policeman of her innocence.
