A scientist discovers a chemical that can be used to make a great cure or a great virus, and a criminal sends ninjas to steal it and kill him. When they can't open the container, they go hunting for 'Copy', who (unbeknownst to him) holds the key to the box. The scientists' own ninjas want to stop them by killing Copy first, and only a small peace-loving village of ex-ninja want to stop the bad guys without sacrificing Copy's life.

Izo is an assassin in the service of a Tosa lord and Imperial supporter. After killing dozens of the Shogun's men, Izo is captured and crucified.
