Five high school seniors from East Great Falls High School in West Michigan are good friends: Jim, an awkward and sexually naïve nerd whose dad offers him pornography and unwanted sexual advice; Oz, on the school lacrosse team; Kevin, the calm leader of the group seeking to lose his virginity to his girlfriend Vicky; Finch, a mochaccino-drinking sophisticate and nerd; and Stifler, a popular but raucous jock who often throws wild parties when his mom is away, and is the only one of the five who has lost his virginity. Dorky classmate Sherman claims that he lost his virginity at a party hosted by Stifler. Kevin prompts Oz, Finch, Jim, and Kevin to pledge to no longer be virgins by their high school graduation.
