前保龄球手洛伊(Woody Harrelson伍迪•哈里森 饰)早年风光无限,曾经在1979年拿过俄亥俄州保龄球比赛的冠军。但是他的荣耀急转直下,在一次重要比赛中,他被对手厄尼(Bill Murray 比尔•默瑞 饰)陷害,失去了宝贵的右手。在此后的十七年里,他只能戴着假手,做保龄球器材生意糊口。 偶然的机会洛伊认识了阿米什人艾什米尔(兰迪•奎德 Randy Quaid 饰),这个羞涩的大男孩身上蕴藏的保龄球天赋令洛伊欣喜不已。他决定将艾什米尔训练成一流的保龄球手,参加一年一度的冠军赛,为自己报仇……Roy Munson was raised to be the best bowler in the world (trained early on by his father). But a fellow bowler, Ernie McCracken and a misunderstanding with some rough punks, leaves poor Roy with the loss of his bowling hand! Not to let this get him down, he gets a prosthetic hand and becomes a travelling sales man. But it's really all down hill for him from that night on until ... One day he meets Ishmael who is Amish and sneaks away from the farm to bowl (his fellow Amish would disown him if they knew)! Roy convinces Ishmael to let him be his trainer and he'll make him the best bowler the world has ever seen. Reluctantly Ishmael agrees to go on the road and shortly afterwards actually finds that life outside the farm is quite fun. Soon their paths cross that of Ernie McCracken who is still a top ranking bowler. While Roy's career and life have landed in the toilet bowl, Ernie is still drawing huge crowds and all the babes! They both square off for the ultimate bowling championship ... to see which one truly IS the champion.
