In 1928 New Orleans, eighteen-year-old Sonny LaSalle is a top prep student and champion amateur boxer -- and he venerates his fraternal twin uncles, Buck and Russell, armed robbers who love their profession. Sonny secretly believes that he, too, is a natural outlaw and persuades his uncles to take him on as a partner. But when a bank job goes bad, Sonny is sent to jail, where he unintentionally kills a policeman who is the son of the most feared lawman in Louisiana, widely known as "John Bones." After nine months in the infamous Angola penitentiary, Sonny makes a harrowing escape and manages to reunite with Buck and Russell. The carefree trio head out for the boomtowns of west Texas, where the money flows as freely as the oil, unaware that vengeance follows close behind, as the cool, calculating John Bones begins a relentless campaign to hunt down Sonny ... no matter what.
