They just wanted to get home for Christmas...but fate had other plans. It's December 1890. A Texas rancher named Big Jim Conyers has a deal with Scottish-born, Wyoming cattleman named Duff MacCallister. Along with Smoke and Matt Jensen, the party bears down on Dodge, Kansas, to make a cattle drive back to Forth Worth. But before they can get out of Dodge, guns go off and a rich man's son is killed.

Trapped in a remote cabin, surrounded by ruthless gunmen, Matt Jensen and his adoptive father Smoke Jensen join forces with their old friend, Preacher, in the greatest fight of their lives. A ruthless cattle baron has waged an all-out war against the peaceful native tribesmen who have become Preacher's friends. In a bloodthirsty bid for land, power, and wealth, the baron's drafted an army of professional killers to destroy the homesteaders - among them the Jensens are the only men brave enough to stand in his way.

On nothing more than a lark, he leaves his family and begins a journey from Ohio westward. Along the way, he runs up against badlands and bad men, loses his freedom, gains his freedom and learns the first rule of the frontier: Do whatever it takes to survive. With ruthless enemies after him - both White men and Indians - he’ll head for a place as brutal as it is beautiful - the wilderness of the Rocky Mountains.

From his Missouri farm, the boy traveled west. In his hand was a Navy Colt given to him by Jesse James. By his side was the old mountain man named Preacher, who would teach young Smoke Jensen everything he needed to fight like the devil and die like a man. And in his heart...was vengeance. His enemies destroyed everything he'd ever loved. But they made one mistake. They let Smoke Jensen live.

Two of the Johnstones’ most legendary heroes—the rugged mountain man known as Preacher and the Scottish clan rancher Jamie Ian MacCallister, here together for the first time—are forced to choose sides in a blood-soaked battle for the heart and soul of a nation divided. This is not the American dream they were looking for. This is a nightmare. A brutal, blood-drenched frontier war that two heroic men must fight and win—or one struggling nation will never come together. For liberty and justice for all.
