Jake (Sean Faris) is the new kid in school. When a beautiful girl (Amber Heard) befriends him, Jake thinks he's set. But instead, her fight-club boyfriend, Ryan (Cam Gigandet), smacks Jake a bloody, black-eyed welcome. Humiliated, Jake then turns to a mixed martial arts (MMA) master (Djimon Hounsou), who teaches him how to fight...and how to walk away. But it becomes obvious that a brutal re-match is inevitable if Jake wants to stop Ryan and his bullying, once and for all.
