新墨西哥州，1879年8月。被阿帕奇人无情地屠杀的骑兵纵队中为数不多的幸存成员试图到达克莱恩堡。在穿越一片充满敌意的土地的路上，痴迷而无情的文森中士将他指挥下的士兵们的意志发挥到了极限。

不折不扣的娱乐冒险片，片中三个主要角色代表着三股力量和思想，一个为民族独立对抗腐败政府的英雄，一个受了英雄蛊惑不惜肝脑涂地的青年学生，以及一个所谓的欧洲阿拉伯人。

Having fled to Mexico from the U.S. many years ago for killing his father's murderer, Martin Brady travels to Texas to broker an arms deal for his Mexican boss, strongman Governor Cipriano Castro. Brady breaks a leg and while recuperating in Texas the gun shipment is stolen. Complicating matters further the wife of local army major Colton has designs on him, and the local Texas Ranger captain makes him a generous offer to come back to the states and join his outfit. After killing a man in self-defense, Brady slips back over the border and confronts Castro who is not only unhappy that Brady has lost his gun shipment but is about to join forces with Colton to battle the local raiding Apache Indians.
