Former MMA champion Case Walker (Michael Hai White) has kept a low profile, winning small-time regional matches after refusing to join the powerful new leagues who push performance-enhancing drugs on their fighters. Walker is convinced by old friend and renowned fighter Brody James (Josh Barnett) to join him in Thailand and train him for a big fight against the undefeated and deadly Caesar Braga (Nathan Jones). During training, Brody is injured. Under pressure from an unscrupulous, high-powered promoter (Esai Morales), Walker agrees to replace James and fight his toughest opponent yet- but only on his own terms.
