Tekken is a film based on the popular fighting game series of the same name. In the year of 2039, after World Wars destroy much of civilization as we know it, territories are no longer run by governments, but by corporations; the mightiest of which is the Mishima Zaibatsu.
In order to keep the masses down, Mishima sponsors the King of Iron Fist Tournament, or Tekken, in which fighters battle until one is left standing, who in turn will receive a lifetime of stardom and wealth.
We are introduced to this violent world through the eyes of Jin Kazama, a teenage street fighter who enters the tournament in order to avenge the death of his mother that he blames upon the Mishima Zaibatsu's most powerful and controlling chairman – Heihachi Mishima.
He knows that the only way to get close enough to Mishima to kill him is to win the tournament, but in doing so, he begins to uncover his own past and inner demons as well as exposing a dark underbelly to Tekken that threatens the very existence of humanity.
