At Adams College, the jocks rule the school from their house on high, the Alpha Beta fraternity. So when a group of socially-challenged misfits try to go Greek, they're instantly rejected by every house on campus. Deciding to start their own fraternity to protect their outcast brothers, the campus nerds soon find themselves in a battle royale as the Alpha Betas try to crush their new rivals.

Tripper is the head counselor at a budget summer camp called Camp Northstar. In truth, he's young at heart and only marginally more mature than the campers themselves. Tripper befriends Rudy, a loner camper who has trouble fitting in. As Tripper inspires his young charges to defeat rival Camp Mohawk in the annual Olympiad competition, Rudy plays matchmaker between Tripper and Roxanne, a female counselor at Northstar.

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.
