Roy Munson was raised to be the best bowler in the world. 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! Roy convinces Ishmael to let him be his trainer and he'll make him the best bowler the world has ever seen.
