Morris Buttermaker, an Alcoholism and former minor-league baseball pitcher, is recruited by Bob Whitewood, a city councilman and attorney who filed a lawsuit against an ultra-competitive Southern California Youth Baseball League which excluded the least skilled athletes (including his son) from playing. In order to settle the lawsuit, the league agrees to add an additional team - the Bears - which is composed of the worst players. Buttermaker becomes the coach of the unlikely team, which includes (among others) a near-sighted pitcher, an overweight catcher, a foulmouthed shortstop with a Napoleon complex, an outfielder who dreams of emulating his idol Hank Aaron, two non-English-speaking Mexican immigrants, a withdrawn and bullied boy named Timmy Lupus, and a motley collection of other "talent". Shunned by the more competitive teams (and competitive parents), the Bears are the outsiders. They play their opening game, and do not even record an out, giving up 26 runs before Buttermaker wikt:forfeits the game.
Small-time promoter/hustler Marvin Lazar (Curtis) sees a potential money-making venture in the Bears that will help him to pay off his debts. After seeing a TV spot about the Bears, he decides to chaperone the baseball team for a trip to Japan in their match against the country's best little league baseball team.
