After seemingly ordinary 15-year-old Leland (Ryan Gosling) stuns his quiet suburban community with a chilling crime, he is sent to juvenile hall where he meets Pearl (Don Cheadle), a teacher and aspiring writer who dreams of making Leland's compelling story into a book. As Pearl digs deeper into Leland's life and the people caught up in it - his mother (Lena Olin), his famous writer-father (Kevin Spacey), and his troubled girlfriend (Jena Malone) - he uncovers Leland's disturbing motive.
