Plot

Charlie Brown and his friends head off to camp, where they encounter Joe Agate, a deceitful bully who claims he’ll teach them the game of marbles—without revealing it’s a high-stakes competition. Once he swindles Rerun out of his marbles, Charlie Brown steps in to help retrieve them for everyone. However, he faces a challenge: Charlie has never learned how to play marbles himself. As he navigates this tricky situation, he must muster the courage to confront Joe and save the day for his friends.
