A dramatic tale of revenge sees Nariko, a fiery red-haired heroine embark on a quest for vengeance against an invading King and his army. The story builds around the ancient Heavenly Sword which once belonged to a powerful deity and can never be wielded by a mortal without it draining their life-force, killing them within hours. When the invading King (played by Andy Serkis) destroys the warrior clan that guards the Heavenly Sword, the clan leader's daughter, Nariko, takes up the sword in a desperate fight for survival.
