In 19th century Japan, a former samurai named Jubei Kamata has abandoned his violent past and is living a peaceful life as a farmer with his children. However, when a group of women from a local brothel offer a bounty to avenge the brutal disfigurement of one of their own, Jubei is reluctantly drawn back into the realm of violence. He joins forces with his old comrade Kingo Baba and a young, eager fighter named Goro Sawada. Together, they venture into the desolate frontier town where the crime took place, hoping to achieve justice.

As they arrive in town, they face the ruthless and corrupt local law enforcement led by Ichizo Oishi, a former Shinsengumi captain who now serves as the town's dictatorial sheriff. Oishi enforces his tyrannical rule with an iron fist, oppressing the vulnerable and maintaining strict control over the citizens. Jubei and his companions must navigate this treacherous environment, contending with their own moral dilemmas and haunting memories from past battles as they strive to fulfill their mission. The journey forces Jubei to confront the man he once was and the choices he now faces between retribution and redemption.
