Meet Dylan Mills. No biggie. High school senior, glee club dropout, and fifth-string hockey goalie, he's a likable underachiever set to attend Party School, a small-town college notorious for raucous celebration. The only thing is, Dylan doesn't party. All he cares about is his high school girlfriend, Rosemary Silversmith. Rosemary is everything to Dylan: she's incredible; his parents adore her. She's, like, the one thing he seems to have done right in his whole life. Unfortunately, Rosemary will not be going to Party School. She's got grades and potential. She's going to one of those colleges parents brag about. She is, frankly, embarrassed by Party School and its hardcore-stoner rap. When freshman year begins, so does the drama; Rosemary starts seeing someone else; Dylan joins a badass underground motorcycle club, even though he doesn't have a driver's license. All is a blur of riotous nights, heartache, weed, and naked shenanigans, until a cheating scandal sends Rosemary running back to Dylan's arms. Now a changed man, he isn't so sure he wants her back.
