Martial arts thriller in which four fighters try to track down the traitor that sent their trainer to prison. Mixed martial arts fighter Tim (Todd Duffee), music store worker Justin (Scottie Epstein), wrestler Mike (Dean Geyer) and boxer Zack (Alex Meraz) all come from very different backgrounds. The man who unites them is Case (Michael Jai White), a brilliant martial arts instructor and former champion fighter. Case is determined that one of the four will triumph in a fighting competition called the Beatdown run by aspiring promoter Max (Evan Peters). However, when Case finds himself in unwarranted trouble with the law, the focus of the four men changes. The person who betrayed Case must have been close to him. Can the four fighters figure out who it was, or will they turn on each other?
