四位驻伊美军士兵接到了回国的调令,然而,一次恐怖性炸弹袭击,改变了他们的命运。军用卡车司机凡妮莎(杰西卡•贝尔 Jessica Biel 饰)被炸成重伤,军医威尔(塞缪尔•杰克逊 Samuel L. Jackson 饰)负责救治,结果不幸截肢。贾马尔(50美分 50 Cent 饰)误杀了伊拉克妇女,从此存下心结。汤米(布莱恩•普莱斯列 Brian Presley 饰)亲眼目睹了战友阵亡,悲痛欲绝。四个人回国后,凡妮莎在校园做体育老师,但是配搭的假肢让她黯然神伤。威尔的妻子发现丈夫的情绪总是失控,而叛逆的儿子也经常顶撞父亲;贾马尔和汤米同时进行了心理诊疗小组,但是两人发生争执,分道扬镳,没想到再次见面却是生死一线……The day after they get the word they'll go home in two weeks, a group of soldiers from Spokane are ambushed in an Iraqi city. Back stateside we follow four of them - a surgeon who saw too much, a teacher who's a single mom and who lost a hand in the ambush, an infantry man whose best friend died that day, and a soldier who keeps reliving the moment he killed a civilian woman. Each of the four has come home changed, each feels dislocation. Group therapy, V.A. services, halting gestures from family and colleagues, and regular flashbacks keep the war front and center in their minds. They're angry, touchy, and explosive: can a warrior find peace back home?
