背景设定在1892年,讲述在一场严峻的反抗暴乱之后,上尉Blocker勉强同意护送生命危在旦夕的夏延酋长及家人返回他们生活的部落。在这段从新墨西哥州前往蒙大拿州草地痛苦又冒险的旅程中,这对前竞争对手遇到了一个寡妇,她的家人们在平原之上被谋杀了。三方要共同合作克服艰难的地形继续上路,还要对抗科曼奇族的敌人以及邪恶凶猛的露宿者。In 1892, after nearly two decades of fighting the Cheyenne, the Apache, and the Comanche natives, the United States Cavalry Captain and war hero, Joseph Blocker, is ordered to escort the ailing Cheyenne chief, Yellow Hawk--his most despised enemy--to his ancestral home in Montana's Valley of the Bears. Nauseated with a baleful anger, Joseph's unwelcome final assignment in the feral American landscape is further complicated, when the widowed settler, Rosalie Quaid, is taken in by the band of soldiers, as aggressive packs of marauding Comanches who are still on the warpath, are thirsty for blood. In a territory crawling with hostiles, can the seasoned Captain do his duty one last time?
