In the year 2039, after wars destroy much of civilization as we know it, territories are no longer run by governments, but by corporations; the mightiest of which sponsors the King of Iron Fist Tournament, or Tekken, in which fighters battle until one warrior is left standing. Jin, a rebellious teenage street fighter enters the tournament in order to avenge the death of his mother that he blames upon the all-powerful head of Tekken. Jin knows that the only way to get close enough to kill him is to win the tournament, but in doing so, he begins to uncover his own past and expose a dark underbelly to Tekken that threatens the very existence of humanity.
