All of the kids at Camp Hope have a weight problem. It's the one place they can go without feeling different. But when the previous owners declare bankruptcy, the camp is purchased by a fitness freak who becomes obsessed with changing his chubby charges into budding body builders. He immediately begins serving them low calorie foods and subjecting them to rigorous exercises. Part of his motivation is greed: he is in the process of writing a book and filming an infomercial on weight loss. When the boys at camp finally rebel, mayhem ensues.
