Set in the Sengoku Period. Retired from ninja duty, Torakage lives a peaceful life in a small village with his wife and son. One day, Torakage’s son is kidnapped by his former master in an attempt to force him to break into a nearby castle and steal the Gold Scroll, the counterpart to her Silver Scroll, the two of which when brought together point the way to a vast treasure. Having no choice, Torakage and his wife sneak into the castle. However, their plan goes awry and the two are caught and turned over to the evil lord.
