Sole survivors of their clan, assassins Azumi (Aya Ueto) and Nagara (Yuma Ishigaki) have one final target: the warlord Misayuki Sanada (Mikijiro Hira). They team with bandit Ginkaku (Shun Oguri) -- who looks like Azumi's slain friend Nachi -- as well as ninja allies, but among them is a traitor. With Ginkaku at her side, Azumi goes after Misayuki, who has assembled a stealth killing squad to stop her once and for all. But just who is Ginkaku?
