It's one hot night near the end of summer somewhere in leafy suburban America, and a bunch of high school kids — from baby-faced freshmen to confident seniors — ride bikes out to their favorite swimming holes, cruise around in cars blaring tunes, wander from house to house thinking that the next party will be better and, with the help of alcohol, try to get sloppy enough to make out with someone. They're all restless, not realizing that years from now, they're going to look back at this aimless freedom as "the best days of their lives."
