Goemon returns to Iga after ten years, only to find his master, Jinen, near death. Before expiring, he tells Goemon that his junior disciple, Hissatsu Jinkuroo, stole half of the Scroll of the Secrets of the Iga Ninja, which contains a map showing the location of the Treasure of Iga. He also gives Goemon the remaining portion of the scroll, with the rest of the map. Jinkuroo, knowing that he doesn't stand a chance in a straight-on fight against Goemon, boldly has himself arrested, hoping to be put in prison, and thus beyond Goemon's reach. How will the trial, and the death duel, turn out?!
