Once upon a time in the Old West, Buck Trammel was a Pinkerton agent with a promising future. But after a tragic incident in a case gone wrong, he struck out for the wide-open spaces of Wichita, Kansas. Working as a bouncer at the Gilded Lily Saloon, he hopes to stay out of trouble. But soon enough, his gun skills are put to the test. The Bower gang shows up, turning a friendly card game with a Wyoming cattle baron into a killer-takes-all shooting match. Buck saves the cattle baron's life, but at the cost of two Bower men. That's when Deputy Wyatt Earp arrives. 

He came west to the Rockies as a young runaway and grew into a legend among the already legendary frontier mountain men. They called him Preacher - a name that would become a monument to all who sought adventure in the savage wilderness of America's untamed west. The only man with the skills to lead a wagon train on the last leg of the rugged Oregon trail, Preacher knows they're headed into trouble. It's hard enough for a hundred greenhorns to survive the wilds of the northwest; being pursued by thieving renegade outlaws and Indians with a thirst for gold makes it damn near impossible.

With Apaches on the prod, ex-cavalry sergeant Sean Keegan, bounty hunter Jed Breen, and ex-Texas Ranger Matt McCulloch take shelter in a West Texas way station - along with a hot-as-a-pistol female bound for the gallows, a spiteful newspaper editor, and a coward with $50,000 who promises them five grand if they'll deliver his blood-soaked stash to his wife. Turns out, Indians might be the least of the problems for the trio, soon to be known as the Jackals. The loot's stolen property of the vengeful Hawkin gang, and these prairie rats are merciless, stone-cold killers.

Rollie Finnegan is a man of few words. As a former Pinkerton agent with two decades of experience under his belt, he uses his stony silence to break down suspects and squeeze out confessions. Hence the nickname Stoneface. Over the years, he’s locked up plenty of killers. Now he’s ready to make a killing - for himself.. There’s gold in the mountains of Idaho Territory. And the town of Boar Gulch is a golden opportunity for a tough guy like Finnegan. But when he arrives, the local saloon owner is gunned down in cold blood - and Finnegan makes a cold calculation of his own. 

As the father of a young Crow tribesman, Preacher would like nothing more than to see the long-time natives and newly arrived settlers live together in peace. Then, the killing starts.... As a family man and frontiersman, Jamie Ian MacCallister is more than happy to help the officers at Fort Kearny negotiate a peace treaty with the Crow nation. Until it all goes to hell.... 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.
