Seth (Jonah Hill) and Evan (Michael Serra) are a pair of unsociable friends with very different personalities. They are about to graduate from high school and are both anxious and afraid of college life without each other. One weekend, the couple's "peach luck" came because they received an invitation to a dance hosted almost entirely by pretty girls on condition that they provide all kinds of alcohol needed for the party. The annoying friend Fogel (Christopher Mintez Price) joined them, getting himself a fake ID card and a stupid pseudonym like "Mike Lavin". At the ball, Seth had his eye on Jules, the organizer, Evan had a crush on Becca, the girl in math class with him, and Fogel chose Nicola, who dressed up excitedly. However, a series of unfortunate coincidences took the three men to a strange place and caused them to clash with officers Slater and Michaels. For the three young men who are about to graduate from high school, it may be the scariest and most shameful night they have ever experienced, but it is also a night worth remembering for the rest of their lives.
