Erik, Ryan, and Cooze start college and pledge the Beta House fraternity, presided over by none other than legendary Dwight Stifler. But chaos ensues when a fraternity of geeks threatens to stop the debauchery and the Betas have to make a stand for their right to party.

The movie will shift its focus on Erik Stifler, the cousin of Matt and Steve, a youngster who is nothing like his wild relations. Peer pressure starts to turn him to live up to the legacy of the other Stiflers when he attends the Naked Mile, a naked run across the college campus. Things get worse when he finds that his cousin Dwight is the life of the party down at the campus
