When their shortstop 'strikes out' permanently, the fun loving 60 to 75 year old 'Kids at Heart', decide to go for their secret dream... to win the Senior World Series. Renaming themselves Big Guns, they get serious and play hard. Maybe just a little too hard. Illegal bats, booze, ringers, and wild women, bring out the worst in them. Making even wise old guys, think twice as they rediscover that love and friendship are more important than winning.
