Stephen Arden (Ralph Bellamy) sends his girlfriend, Amanda Cooper (Ginger Rogers), to his good friend, Dr. Tony Flagg (Fred Astaire), who is a psychiatrist, and wants him to find out why she keeps postponing their marriage. Amanda falls for Tony, and he uses hypnosis to plant in her an unconscious hatred of him and love for Stephen. Tony then realizes he has fallen in love with her as well and must revert the hypnotic suggestions before she marries Stephen.—Les Adams
