As a child, Bill witnesses the murder of his family by four robbers. Fifteen years later, he embarks on his revenge. During his quest, he crosses paths with Ryan, an ex-con who wants the money the robbers owe him. 向西是命，向西有情。经典就是经典。又一部经典意大利西部片。 比尔·马捷达幼时因匪徒的袭击而全家遇害，自己因为其中一位袭击者的暗中帮助而侥幸逃命，十五年来一直在训练枪法，打听仇人下落。而最近他却和刚从监狱放出来的莱恩（李·范·克里夫 饰）不停的扯上联系，二人总是如同约好一般在各种场合同时出现，并且在这个过程中也互相了解对方。莱恩和比尔一样也在复仇，而他貌似也和比尔童年的悲惨遭遇有着千丝万缕的联系。
