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).
