After defeating Kazuya Mishima in the King of Iron Fist Tournament 2, Heihachi Mishima reclaimed the Mishima Zaibatsu and created the Tekken Force, a paramilitary organization dedicated to protecting the company. One day, a squadron of Tekken Force soldiers searches an ancient temple in Mexico as part of an excavation project and is almost wiped out by the mighty Ogre. Heihachi Mishima's only hope is his grandson Jin Kazama, who lives with his mother Jun unaware of his heritage. When Ogre attacks his home and presumably kills his mother, Jin goes in search of his grandfather and learns the family martial arts. On his nineteenth birthday, Heihachi announces the King of Iron Fist Tournament 3, hoping to use Jin to get Ogre out of the way.
