What is the full name of the person who accompanies the "good luck charm" to Europe?
Superstitious New York gambler Joe Baldwin, 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. He also gives his old friend Frank Brent cash to save his cab business and visits an orphanage in Louisville with his sister, where he meets Betty McKay, a pretty teacher who scoffs at his philosophy.
She scolds him for wishing for rain on the day of the Derby to aid his horse, who runs best on a muddy track, because the orphans plan an outdoor party. Although it rains as wished, Sarcasm loses the Derby, and Joe is convinced that it was because the orphans were pulling against him. In an attempt to repair the damage before the Preakness, Joe throws the orphans a lavish party, hiring clowns and other entertainment. To Betty's surprise, Joe is as excited as the children, and they fall in love.
After Sarcasm wins the Preakness, Joe returns to New York, where Jean is back from Europe. Joe tells her that he will not be seeing her any more because he is going to marry Betty, and she cajoles $50,000 from him as a final "luck insurance" payment. Before Joe shows up with the check, however, Paul arrives at Jean's apartment. They argue when he sees that she plans to run out on him with the money.  Jean threatens him with a gun, and during a scuffle, kills her.
