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. Before losing his hand to some angry bowlers he scammed, Roy was a bowling phenomenon. Twenty years later, Roy takes a gifted Amish bowler under his wing, and, in a comic series of raunchy adventures, they go on a mission to beat Roy';s old rival Big Ern.
