Heavenly Sword is a dramatic tale of revenge that sees Nariko (Anna Torv), a fiery red-haired heroine, embark on a quest for vengeance against the invading King Bohan (Alfred Molina) and his army. Once considered the failure of a legendary prophecy, Nariko must wield a sword that was ultimately meant for another. This ancient Heavenly Sword, once belonging to a powerful deity, can never be wielded by a mortal without it slowly and inevitably killing them. For Nariko, it is a race against time to avenge her clan before her life is irreparably overtaken by the omnipotent Heavenly Sword.
