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.

The nerds are now in control of the university, as a result of Lewis Skolnick and the rest's actions in the two previous movies. A new generation of sportsmen arrive, however, determined on winning the school back. 

Lewis and his nerdy friends attend Booger's wedding to the daughter of a rich politician, but nerd-haters in the family do everything possible to prevent the wedding going ahead.
