Bill has just graduated and he can't wait to start his adult life at the age of 18. So he waved goodbye to his comfortable home, moved into a bachelor apartment and moved toward the "real world" of adults. In order to reduce the burden of rent, he asked his good friend Tom to move in together, which led to a lot of questions. First of all, Tom is loyal to his girlfriend, but his girlfriend regards their love as a child's play; on the other hand, in order to match his "adult" identity, Bill abandoned his girlfriend Anita. Angry Anita began to date with a middle-aged David. Unexpectedly, David is not only married, but also a father! This group of 17-and 18-year-olds made a mess when they first stepped into the adult world. How can this period of "crazy wild life" end?. The film was written by Cameron Crowe, who in his early days represented the masterpiece "Open American Universities" and recently conquered the film world again with "conquering the Sea of Love".
