Eight elite fighters - prisoners from maximum security prisons around the world - are brought together by a powerful underground gambling syndicate for a secret, survival-of-the-fiercest battle competition. The prize: freedom for the champion - and a payday of millions to the organizers. Except the syndicate really doesn't plan on allowing anyone to walk free. Scott Adkins (the fearsome Weapon XI in X-Men Origins: Wolverine) returns as Boyka in a spin-kicking, iron-fisted, ground-and-pound fury of martial arts mastery. With the odds against him overwhelming, Boyka will take on the syndicate his way. If his gambit works, it might send the whole scheme crashing down around them.
