Three couples go on a camping trip in the woods of southern California during the summer, where a deformed man is stalking their camp.

The director of a failing summer camp decides to invite campers from ten years ago for a free weekend event, hoping that he can trick them into fixing up the place and also get their families to provide them some financial support. The boys and girls return to the camp and play pranks on each other and try to score with the other campers and the staff.
