Undisputed II: Last Man Standing

Undisputed II Last Man Standing is a 2006 directtovideo martial arts film and is the sequel to the 2002 boxing film Undisputed. The film stars Michael Jai White, Scott Adkins, Eli Danker and Ben Cross, and was directed by Isaac Florentine. White portrays exboxer George Iceman Chambers, a role originally played by Ving Rhames in the first film. The film is followed by the 2010 sequel Undisputed III Redemption, which continues the story of Russian prison fighter Yuri Boyka, played by Adkins.

During the fight, Chambers is somewhat taken by surprise at the flurry and variety of Boykas attacks, but manages to hold his own through the first round by keeping his distance, staying calm, and dealing out painful punching combinations whenever possible. At the end of the first round, Chambers takes a few sips of the spiked water, causing him to lose on the second round when he loses consciousness and falls to Boykas flying kick. Following the match, Steven hangs himself out of guilt. Later, Chambers confronts Boyka over the sedative incident after Boyka learns that his gang spiked Chambers water behind his back, Chambers demands a rematch to ensure his release. Chambers receives training in mixed martial arts from Crot, who was a former soldier and the one who trained Boyka in his fighting style.Once the rematch begins, it is apparent to all the viewers that the combatants are evenly matched and Chambers is more impressive in his style. The fight is long and intense, with flurries of combinations, grapples, and throws traded between the two. Eventually, Chambers realizes that Boyka will not lose consciousness, will not submit, and will likely knock him out if the fight goes on too long. Chambers alters his strategy and manages to get Boyka in a joint lock and ends the fight by breaking Boykas leg, proving that he is the undisputed new champion of the prison. Shortly thereafter, Chambers is released from prison and uses his winnings to buy Crots freedom as well. In a final scene, he wheels Crot to a train station to meet with his estranged niece in a happy reunion. Crot thanks Chambers for giving him the remainder of the winnings to start his life again, while Chambers expresses his gratitude for the help and training. Crot then meets with his long lost niece and the two embrace. ........
