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.

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.

Orphaned at the age of seven and adopted by Indians, Jami Ian MacCallister grew into a man more at ease in the wilderness than among men. But when the westward strike drove him across the Arkansas Territory into Texas, he finally found himself a home — in the middle of a bloody war. Texans like Jim Bowie and Sam Houston were waging a fierce struggle against Santa Ana’s Mexican army and Jami MacCallister made the perfect scout for the fledgling volunteer force. 

Matt Cavanaugh was 9 years old when a band of outlaws slaughtered his family. Now Matt is 18, honed by hardship, schooled in the mountain ways and carrying the last name of the man who raised him: Smoke Jensen. With Smoke's wisdom, Matt's own courage and just enough money to start a life, Matt Jensen begins a relentless hunt for the outlaws who murdered his family in cold blood.

It's the dawn of a new century. But on the vast Sugarloaf Ranch not much has changed since legendary gunfighter Smoke Jensen and his wife Sally tamed the land two decades ago. Raising cattle is still a dangerous business - and just as deadly as ever. When Smoke is injured swapping bullets with some cow thieves, Sally puts out a call for help to Matt, Ace, and the rest of the Jensen clan. But time is running out. The bloodthirsty rustlers are ready to strike again - and there are lots more of them. And the Sugarloaf's last defense is Smoke and Sally's next of kin.... 

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.

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.

The cattle town of Chugwater may not look like much to outsiders. But for Duff MacCallister and the determined settlers who’ve staked their futures here, it’s a land of opportunity. That’s why the whole town is fired up by the latest news. Young railroad developer Jacob Poindexter wants to run a rail line through Chugwater, making it easier to transport cattle. Everyone is on board with the plan — at first. Duff begins to suspect that Poindexter is only after the most valuable land, and he’s using strongarm tactics to force reluctant ranchers to sell.

Their father is Luke Jensen, supposedly killed in the Civil War. Their uncle Smoke is one of the fiercest gunfighters the west has ever known. It's no surprise that the inseparable Ace and Chance Jensen have a knack for taking risks — even if they have to blast their way out of them. Chance is a bit of a hothead, good with his gun and his fists. Ace is more of a thinker, sharp as a snake bite and just as deadly quick. Their skills are put to the test when two young ladies ask them to protect their struggling stagecoach line from a ruthless, bloodthirsty mine owner.
