Superstitious New York, New York gambler Joe Baldwin (Onslow Stevens), owner of the thoroughbred racing horse Sarcasm, believes that luck can be bought with charitable deeds. Before the Kentucky Derby, to "buy luck," he finances an expensive trip to Europe for gold-digger Jean Jason, his "good luck charm," not knowing she is taking her lover with her, gigolo and sometime artist Paul Vinette (Vinton Hayworth). He also gives his old friend Frank Brent cash to save his taxi and visits an orphanage in Louisville, Kentucky with his sister, where he meets Betty McKay (Helen Mack), a pretty teacher who scoffs at his philosophy.
