The Old West comes alive in this epic tale of lawless desperadoes and a man seeking redemption through the love of a good woman. Things become increasingly dangerous for Bill Barton as his cattle rustling buddies in Missouri, including Frank and Jesse James, turn to the ways of gunslinging outlaws. Living a double life as a southerner named Leroy Thompson, Bill works to guard his real identity when south of the Mason-Dixon Line. He knows the promise of his new life would come to a violent end if his Confederate partners ever found out he had been a Union spy during the war.
While on a cattle rustling foray into Missouri, Bill's life becomes even more complicated when he accidentally runs into the love of his life, Cole Younger's sweetheart, Lucy Breeden. Lucy feels as deeply for Bill as he does for her, which puts the couple on a collision course with the bloodthirsty Cole Younger, who believes that if he can't have Lucy, no one will.
