School is out for the summer and Charlie, Linus, Schroeder, and Pig Pen are planning to spend it reading every comic book, watching television, playing baseball, and playing classical music. However, Lucy tells them that she signed them up for camp. The girls are eager to go, but the boys hate the idea. The boys shove each other to get on the bus, while the girls line up in order. At camp, Charlie is chosen as captain of the boys' camp. The boys and girls have a swim race which the girls win easily. Then they have a softball game, which the boys lose with only one run. Other competitions are just as lopsided.
