Undisputed II: Last Man Standing (2006)

Wrongfully accused. Unjustly imprisoned. Now he's fighting back.

Heavyweight Champ George "Iceman" Chambers is sent to a Russian jail on trumped-up drug charges. In order to win his freedom he must fight against the jailhouse fighting champ Uri Boyka in a battle to the death. This time he is not fighting for a title, he is fighting for his life!
