When school ends for the summer, Gerry Garner’s parents send him to Camp Hope, a weight loss camp for boys. Initially reluctant, Gerry meets enthusiastic camp counselor Pat, and befriends the other campers, who have smuggled in enough junk food for the entire summer. The first night at Camp Hope brings the revelation that the original owners, the Bushkins, have declared bankruptcy and the camp has been bought by fitness entrepreneur Tony Perkis, who plans to transform the camp’s weight loss program into a best-selling infomercial.
