Seven years after a daring bank robbery involving an anti-tank gun used to blow open a vault, the robbery team temporarily puts aside their mutual suspicions to repeat the crime after they are unable to find the loot from the original heist, hidden behind a school chalkboard. The hardened artilleryman and his flippant, irresponsible young sidekick are the two wild cards in the deck of jokers. 《越战猎鹿人》导演迈克尔．西米诺初露锋芒的处女作。故事有趣，角色鲜明，既有动作又有笑料，娱乐效果相当高。克林特．伊斯特伍德饰演抢匪冲天炮，他跟乔治．甘迪等搭档枪劫政府的保险箱，但事成之后赃款却神秘失踪。冲天炮被怀疑暗中侵吞这笔钱，只好展开逃亡。外号飞毛腿的流浪汉杰夫．布里奇斯救了他，两人成为新搭档。后来冲天炮终于向老朋友澄清误会，飞毛腿趁机建议他们重新组合起来再抢劫同一保险箱，只是他们这次逃走时遭遇了麻烦。四位主角演来各有特色，其中以杰夫．布里奇斯最抢镜头，曾提名奥斯卡最佳男配角奖。
