As summer vacation kicks off, characters like Charlie Brown, Linus, Schroeder, and Pig-Pen are packed with excitement, eager to spend their days indulging in comic books, television, baseball, and classical music. Their plans are simple and carefree, reflecting classic childhood joys. However, their enthusiasm is quickly dashed when Lucy informs them that they have all been enrolled in summer camp. While the girls, including Lucy, Frieda, and Sally Brown, display eager anticipation for the adventure ahead, the boys, which include Charlie Brown, Linus, Schroeder, and Pig-Pen, are clearly less enthusiastic. They show their dismay by jostling one another as they line up to board the bus, contrasting sharply with the orderly and eager girls who stand in a neat line.
Upon arriving at camp, Charlie Brown is appointed as the captain of the boys' team, setting the stage for a series of friendly but competitive events. The campsport competitions begin with a swimming race, where the girls outpace the boys decisively, claiming an obvious victory. This is followed by a softball game in which the boys are thoroughly beaten, managing to score only a single run against the girls. As the competitions continue, the results remain quite one-sided, and the boys find themselves increasingly dispirited by their lack of success and mounting losses. Their morale takes a further hit as they realize how outmatched they are in these early contests.
In a moment that sparks some inspiration, Charlie Brown and Shermy watch Snoopy—the beloved dog character—engaged in an arm-wrestling match with the boys. Witnessing Snoopy's display of strength and determination motivates them to plan a comeback. They organize an arm-wrestling contest, with Snoopy—the "Masked Marvel"—representing the boys. Determined to prepare, Snoopy undergoes an intense training regimen, consuming a nasty-tasting camp meal, performing various exercises, and drinking a vile yet nutritious concoction. His efforts culminate in a dramatic match against Lucy, who takes on the role of the opponent.
The face-off between Snoopy and Lucy is tense and grueling, with both showing signs of fatigue as they sweat and struggle through the contest. The climax of the match features Snoopy kissing Lucy, which enables him to pin her hand and seemingly win. However, Lucy claims the kiss was a foul, and she declares herself the winner, leaving Snoopy momentarily disappointed but proud of his effort. The contest exemplifies the playful rivalry and camaraderie that runs through the camp activities.
