Eddie Bartlett, George Hally, and Lloyd Hart meet each other in a foxhole during the final days of World War I. Following the war's end, Lloyd starts his law practice, George becomes a bootlegger, and Eddie becomes a cab driver. While unknowingly delivering a package of liquor to Panama Smith, Eddie is arrested. Eddie helps secure an acquittal for Panama, who in gratitude provides money to pay Eddie's fine. They go into the bootlegging business together. Eddie uses a fleet of cabs to deliver his liquor, and he hires Lloyd as his lawyer to handle his legal issues. He encounters Jean Sherman, a girl he formerly corresponded with during the war, and gets her a job singing in Panama's club. Eddie wants Jean as his wife, giving her an engagement ring that he asks her to hold until he's saved up enough money to quit the criminal rackets.
