After breaking up for the summer, the four friends regroup for a party held by Stifler (Seann William Scott), their overtly sex-crazed class clown and good friend. His party is shut down thanks in part to the neighbors calling the police. Kevin (Thomas Ian Nicholas) is inspired by his brother to make his summer with his friends count by renting a beach home. He, Jim, Oz and Finch plan to take off to a beach house together, where they intend to spend the summer. Kevin realizes a problem and worked out that they can only afford the house if they have a fifth member to work along with them. Stifler takes charge of much of the organizing, often ending up leading the group in their misadventures.
Oz (Chris Klein) is miserable, being away from his girlfriend Heather (Mena Suvari) who is in Spain. They proceed to start havingphone sex to vent some of their loneliness, which ends up being interrupted by Stifler. Heather later shows up early to the party, ending the short storyline that Oz is involved in.
