Crump's Colossal Combined Carnival Show barely survives financially by hiring thieves and pickpockets to rob customers. One day, clubman Jack Hamilton buys the circus when his car breaks down on his way to meet a deadline to avoid bankruptcy and he needs the circus tractor to haul his auto out of a ditch. Hamilton leads the circus to financial success and falls in love with Gypsy, the ticket-taker. To convince Jack to marry Gypsy, her supposed mother, fortune-teller Carlotta, says that she was kidnapped as a baby and shows Jack a photo in which he recognizes Gypsy's mother as the wife of Andrew Pomeroy, the financier who ruined him.
