After the war, Banes uses forged papers to join the carpet-bag government, inflates taxes, and threatens foreclosure on the ranch. Graham raises money by selling a herd of mustangs to a dishonest officer of the Juaristas, a rebel faction in Old Mexico fighting Emperor Maximillian. He dodges U.S. And French army patrols and rescues Carlos from conscription into the Mexican revolutionary forces.
With the ranch safe and Barnes in prison, they join a cattle drive, but Sammy is captured by Comanche and Carlos' father is killed. In Abilene, John meets the love of his life, Christina, but before he can return to the ranch and tell his parents, the escaped Barnes murders his mother and father and burns his home. A vengeance trail takes Graham on a tour as law-enforcement officer through Fort Worth Hell's Half Acre and Abilene, Kansas. Christina demands he choose between her hand in marriage or pursuit of the murderer, and rewards him with cozy home and a baby boy.
