Honor for a man, honor for a samurai, and honor for a servant of the shogunate. Their codes of justice now clash!
In 1735, three years after the great famine of Kyoho, the feudal domain of Inaba in the San’in Region seemed to have regained a semblance of stability. However, Lord Deputy Minayoshi Araki (Go Wakabayashi) receives a report that Juzo Matsumiya (Yuuki Meguro) was dispatched from the shogunate to Inaba as an instructor of swordsmanship. Sensing something is wrong, Araki orders his right-hand man, Taigo Funase (Takeo Nakahara), to keep an eye on Matsumiya.
Also residing in the Inaba domain is a swordmastr named Daihachiro Harada (Takehiro Hira), a young samurai called Hiroki Kagawa (Tomohito Wakizaki) and his older sister Yuki (Tamao Sato). They lost their beloved father when they were young, but Harada strives to facilitate his young charge Kagawa’s lifelong dream to train in swordsmanship in a neighboring domain. Funase reports to Araki that he has acquired a secret letter by Matsumiya to the shogunate. The letter cryptically states, “I have discovered all about the Inaba domain.” Araki also hears that the shogun’s envoy, Takamine Nishizaki (Asahi Kurizuka), is fast approaching the domain. If Nishizaki is able to liaise with Matsumiya, the Inaba domain will surely be eradicated by the shogunate. Araki must quickly make a fateful decision. What will this mean for Harada, Funase, Kagawa and Yuki…?
