Just before his first performance his act is shut down by capricious manager Ross Ormond who wants Gallico's brilliant buzz saw effect for the act of The Great Rinaldi, an established star. With this defeat, and the humiliation of having already lost his wife Claire to Ormond, Gallico decides it is time to take matters into his own hands.
