在这部虎豹小霸王前传片中,还记得一九六九年由银幕硬汉保罗纽曼、美国金童劳伯瑞福领衔主演的经典西部名片《虎豹小霸王》？本片即描述布区卡西迪以及日舞基德这二名枪法了得的亡命之徒，犯下一连串银行抢案的故事。
Midwest preacher's son 'Butch' Parker gets a pardon after a well-deserved year in jail on promise never again to commit crimes in Wyoming. He befriends naive ranch hand Harry, would be-crime king the Sundance Kid. In relative Mike Cassidy's gang, they rob targets defended by the ruthless Pinkerton Agency men. The gang becomes the Wild Bunch after Mike is killed and Butch takes his place, by now reputed Robin Hoods as the railroad is so unpopular. Having faked their death, they retire to a pueblo in Mexico with shared girl-friend, photographer Etta Place. Sergeant Sanchez wants the bounty on their heads, or a larger share of their loot.
