A camp for chubby kids is invaded by a fitness instructor who spoils their fun and presses them into a strict calisthenics program. After weeks of grueling discipline the kids conspire to overthrow the dictator and win back their freedom.
Fitness guru Tony Perkis has bought a summer camp devoted to helping the overweight child lose some pounds. Some of the kids, however, including young Gerry Garner, think he doesn't have their best interest in mind. Perkis seems more concerned with his pocket book than with his campers when he uses them as subjects in an exercise video he hopes will make him millions.
