Camp Hope is a summer camp for fat kids; it is also the locale of this Disney family comedy. All of the kids at Camp Hope have a weight problem. It is the one place they can go without feeling different. But when the previous owners declare bankruptcy, the camp is purchased by an obnoxious 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. The boys at camp rebel and mayhem ensues.
