Matt Stifler, the younger brother of Steve Stifler, is eager to enter the family business of making porn films so he can prove himself to his older brother. After Matt plays a prank on the school band, the school's guidance counselor Chuck "The Sherminator" Sherman, who attended high school with Steve, decides that a worthwhile punishment would be for Matt to attend band camp. Matt is initially disgruntled by the idea but soon agrees to it, interested in the notorious sexual behavior of band camp girls (citing Jim's marriage and sex life with Michelle as an example).

Erik is then welcomed by his cousin, Dwight Stifler, the leader of the Beta House fraternity, who invites Erik, Cooze, and Bobby to a Beta House party. They meet Wesley, the rush chair of Beta House who experiences Blackout (drug-related amnesia) after drinking alcohol, and learn how they can gain eligibility to pledge for the Beta House. They are also informed by Dwight that the Geek House, formed by wealthy nerds, has been trying to shut down Beta House.
The film begins with Rob entering his bedroom, and attempting to masturbate with a peanut butter and jelly sandwich (similar to the apple pie scenario in the first film). While he is doing this his dog, Frizzie, tries to eat the sandwich, and Rob's little brother Cody takes a video of the ordeal. Later, Rob meets with his friends, Nathan and Marshall Lube, at school. Nathan reveals that his girlfriend, Dana, has pledged to abstain from sex until marriage despite the fact that she has already slept with six other people. Rob talks to Heidi, a girl he is attracted to, and Stifler. Stifler states that if Rob doesn't make a move on Heidi, he will. In class, Lube has a vivid fantasy about a group of cheerleaders, particularly one named Ashley Lawrence. Rob and Heidi meet later in the school library where she discloses that she is a virgin, and wishes to just "get it [sex] over with". At the school dance, Nathan tries to get to second base with Dana, but only manages to offend her due to her abstinence pledge. Rob attempts to tell Heidi how he feels about her but is interrupted by Nathan and Lube. He eventually finds her in the library about to have sex with another student, and drops a lit candle in a bin in shock. This sets the library on fire, which sets off the water sprinklers.
