Korean pop star Rain stars as heroic, deadly Raizo. Trained from childhood in the way of the Ozunu Clan ninja, he is stalked by fellow warriors for breaking free of them and their iron-willed dojo patriarch - and is on the run with a Europol agent (Naomie Harris) who has proof the clan sells assassination services to governments. The action is start-to-finish - fast, fierce, filled with weaponry and awesome athleticism. Fear not the weapon, but the hand that wields it.
