High school buddies, Joe "Coop" Cooper (Trey Parker) and Doug Remer (Matt Stone), invent a driveway
game, a combination of baseball and basketball. As they move into adulthood, their increasingly popular game goes
big-time with the help of eccentric billionaire Theodore Denslow (Ernest Borgnine), the founder of the
National BASEketball League and owner of the Milwaukee Beers. After Denslow chokes to death on a hot dog, the
team is left in Coop's hands. The future of the game is threatened when Denslow's widow (Jenny McCarthy)
and industrialist Baster Caine (Robert Vaughn) scheme to gain control for themselves.
