Yuri Boyka, who was seriously injured in Undisputed 2 in the rematch against ex-boxing champion Chambers, because he did not give up in a hopeless situation, is back. He became friends with a fellow prisoner and saves his life by helping him escape, because otherwise provided in the boxing ring was his death. In uncompromising brutal Final Battle is Boyka (pain) can enforce with great willpower against the Champion Dolor despite renewed severe leg injury. He breaks the opponent's leg, as both in rotation Kicks with legs collide against each other. Strong film with incredible artistic battle scenes excellent martial artists who have known each other for. T. from other action movies. Undisputed 2 is still significantly better, however 5 points.
