In the Edo period───.
A daimyo and the governor of Nagasa District "Shibata Samon", joins forces with "Daikokuya Rihei" in committing evil deeds, spending their days with their pockets filled.
But one day, they hear the news that a spy may have been sent to investigate them. Is the spy an official, or perhaps from someone who is jealous of Samon's wealth and trying to bring him down.
If there is a spy among the people, then they ought to catch them and teach them a lesson───.
"───Odaikan-sama, how about setting a trap here?"
"Are you trying to lure out the spy?"
"Yes, my lord───Rather than hiding carelessly, if we do our evil deeds openly, then the spy will definitely come out."
"That's true... We'll just have to keep a tight net and make sure they can't get away."
"It would be nice to recruit the spy as well───And to do that, of course, if you can spare me your funds."
"Fufufu, very well───You're so evil, Daikokuya."
"No, not at all, not as much as you, odaikan-sama... Fufufu───"
Thus, to protect themselves, Samon and Rihei carry out their plan immediately.
