Jed Cooper 是一个粗暴和无文化的偏僻地区设陷阱者,他和二个伙伴当上了军队的侦察兵,在遥远的俄勒冈军队堡垒工作,而缺乏经验的新兵Jed监督他们,Jed 忽然想过安定的生活,决定需要一个女人来开始这个计划,于是选择Corinna Marston,她是战线下一个堡垒的指挥官Marston上校的妻子。Marston来到他们的堡垒,并对指挥官Riordan上尉宣布,在印第安人攻击下,他的堡垒沦陷了,并且失去了大部份人马……Crude and uncivilized backwoods trapper Jed Cooper and his two partners sign up as scouts in a remote Oregon army fort, manned chiefly by untrained rookie soldiers. Jed, flirting with the idea of leading a more settled life, decides he needs a woman to start the process, and selects Corinna Marston, the beautiful young wife of Colonel Marston, commander of the next fort down the line. Marston arrives and announces to commanding officer Captain Riordan that he has lost his fort and most of his men to an Indian attack and that he, as ranking officer, is assuming command. Riordan, a young, but sensible officer, is outraged when he learns that Marston, posted out west for having lost his 1500-man command during a Civil War battle, has ordered the entire fort's complement, totally unprepared for combat and outnumbered, to march out against experienced Indian warriors.
