Vietnam 1973. After a brutal Vietcong attack, American sniper Calvin Hart and his injured spotter Thomas Newton must fight their way through enemy territory with limited resources to reach their rescue team. While communicating via radio with their sergeant, the soldiers become the targets of bounty hunters, assassins and the VC's best sharpshooters. With Newton dying fast and Hart losing his sanity even faster, the pair faces immeasurable odds made worse by a haunting obligation waiting back at home.
Upon their arrival in Flat Oak for a semi-centennial celebration, renowned shootist Mance Dixon and his friend Clabe run into a surviving victim of a vicious vigilante group known as The Tramplers. Offering her protection once in town, matters become complicated when a con artist posing as a mythologic killer lends his services to a large cattle baron heading the hired killers. After further run-ins with a demented family and a trio of scalphunter brothers, all roads lead back to Flat Oak for an inevitable massacre that will forever alter the fate of the once-peaceful town.
