Bronco Wade and his older friend Curly hightail it out of Texas when the Sladek family of the Trigger Bar Ranch go on a rampage. Three of the Sladek brothers have been murdered, and if Bronco and Curly are caught, they'll hang. Fifteen years later, the two friends are following a herd of cattle when they discover that the animals belong to the land-hungry Sladeks, who have been moving most of their stock to the free grass in Montana Territory. Bronco and Curly plan a stealthy getaway, knowing that to be captured by the Sladeks means certain death. But all of that changes when they learn that Curly's long-lost daughter, Charity, has been reared with the Sladeks and is riding with the herd. A stampede, dangerous trail hands, and marauding Arapaho stand in the way of the rescue of young Charity. Ultimately, the trail leads them back to the Trigger Bar, where only Bronco's skill with a gun can possibly save their lives.
