A 12-year old boy inherits the Minnesota Twins in this baseball comedy that is aimed toward younger viewers. Young Billy, a normal twelve-year old, is nuts about baseball and knows almost everything there is to know about the game. He should, his grandfather owns the perennial losers, the Minnesota Twins. When grandpa dies, he leaves the Twins in Billy's hands. Naturally the players are skeptical, especially after Billy designates himself as team manager. But with a combination of guile, knowledge and determination, Billy earns their grudging respect and the team begins a winning streak. Initially, Billy reminds the team that baseball is supposed to be fun, but he soon forgets that as he becomes increasingly involved in the adult world of competition, management and team politics. His three friends are angered that he no-longer has time for them. Billy gets made when the first baseman starts going out with his mom. Eventually the burned out Billy must again learn how to be a kid.
