Former baseball pro, ‘Coop’ Dailey, sells peanuts in the stands of the Bisons, a struggling major league team. His young son, Christie, with a passion for baseball, serves as the team’s bat boy. Coop discreetly coaches the team by sharing invaluable tips with his son, who then conveys them to the team manager.

After a series of events, Christie, impressing the niece of the team’s former owner, secures his father’s vending job back and also lands an unexpected role as the Bisons’ youngest-ever manager in a daring publicity move. However, as fate would have it, Christie falls sick just before a crucial game. Coop steps in as the team’s manager, leading the Bisons to an inspiring comeback, clinching the pennant and paving their way to the World Series.

This movie was remade into a TV movie in 1979.
