When his daughter is murdered, William Duncan takes the law into his own hands, setting out on a quest for retribution. After killing the street thug responsible for her death, he finds himself in the middle of a war with the thug\'s brother, father, and their gang, who are equally hell-bent on getting even. What ensues is a tense back-and-forth game of vengeance. By the end, William comes to find that the quest for revenge never has a winner.
The film's plot follows that of the game closely. Nariko, a member of an ancient tribe who have guarded an ancient magical sword for thousands of years, is charged with bringing the sword to its destined wielder, a deity reincarnated who will bring peace to the land. But on her quest, Nariko must wield the sword herself against the forces of King Bohan, who wishes to possess the weapon himself.
