Veterano Infiltrato, Vendetta Totale

After veteran Kyle’s entire family is massacred by a gang, he goes undercover in the Iron Curtain Society. He saves the acting chairman by knocking out an opponent with one punch. While investigating his sister’s death, he accidentally learns the true cause of his wife’s death. He then joins forces with the chairman to instigate a three-way melee, kills the leaders of two major gangs, defeats the military-industrial tycoon behind the scenes, and completely destroys the criminal empire.
