Steve Bennett (Bob Hope) is a stockbroker in Miami, Florida who has just accepted a position working for a man named T.R. Ralston (Edward Arnold (actor)). He is persuaded by Ralston's beautiful niece Gwen Saunders (Paulette Goddard), to invest a sum of $10,000 that she needs doubled in 24 hours. Ralston has promised Gwen that if she raises $20,000 he will double it, but has been working behind her back to prevent her from raising the initial funds.
