About three hundred years ago, in the fifteenth year of Yuan Lu (1702), the fifth generation of generals Gangji implemented the policy of calming the people, and the people lived a stable life. The young samurai Aoki Zuoweimen (Okada Junichi) came to Edo from Shinzhou in order to find Shibei Kanazawa (Tadashi Asano), the enemy who killed his father. But his swordsmanship is poor, in fact, he can not complete revenge at all. Zongzuo Weimen settled in a dilapidated hut and opened a small private school to make ends meet. Zongzuo Weimen had a secret affection for the beautiful widow Saizhi (Lihui Miyazawa) who lived at the opposite door. Later, Zongzuo found Kanazawa, but the enemy had put down his knife and lived a normal life with his wife and children. Zongzuo began to think about what revenge meant. On the other hand, the samurai of Akuho clan came to lurk in this area, waiting for an opportunity to avenge the unjust lord. They are all for revenge, what will be the end?
