Head strong Thomas Dunson starts a Texas cattle ranch together with the assistance of his loyal trail hand, Groot, Matthew Garth, and his protégé, an undercover Dunson took under his wing when Matt was a boy. Looking for money following Civil War, both Matt and Dunson lead a cattle drive to Missouri, at which they are going to find a better price than locally, but the man and his willful young partner begin to butt heads.
