A black belt loses everything, keeps his morals and wins the big prize.
Great fight scenes both in and out of competition mixed martial arts run through this film. A black belt that has his own fighting technique and a dojo guides his students to put avoiding fights above all else and eventually gets pulled into a fight to save someone that takes advantage of him and ends up destroying a friend, his marriage and possibly his beliefs.
A fateful event leads to a job in the film business for top mixed-martial arts instructor Mike Terry. Though he refuses to participate in prize bouts, circumstances conspire to force him to consider entering such a competition.
