Morris "Mud" Himmel has a problem. His parents desperately want to send him away to summer camp. He hates going to summer camp, and would do anything to get out of it. Talking to his friends, he realizes that they are all facing the same sentence: a boring summer camp. Together with his friends, he hatches a plan to trick all the parents into sending them to a camp of his own design, which would actually be a parent-free paradise. Blackmailing former drama teacher Dennis Van Welker into helping, they must convince the parents that the camp is genuine, and that they aren't allowed to visit.
One of the kids mentions if the concept they are doing for a summer camp could work for a college as well. This concept would be realized in the 2006 film Accepted
Judging by the fact they went through a car wash in Shamokin, it implies that the camp is located in Pennsylvania's Coal Region. In the scene where Polk goes to "Chez Cheez", trying to locate Dennis Van Welker, he finds a postcard on the company bulletin board, which Denis sent from vacation. It indicates that the location of Chez Cheez, and possibly the entire movie is in Pittsfield, PA.[1]
