The film's plot follows a traditional theme, with Zatoichi (a blind swordsman) coming to the defense of townspeople caught up in a local yakuza gang and being forced to pay excessive amounts of protection money. Meanwhile, Zatoichi befriends a local farmer and her gambler nephew and eventually offers his assistance to two geisha siblings (one of whom is actually a man) who are seeking revenge for the murder of their parents. The siblings are the only survivors of a robbery and massacre that was carried out on their family estate ten years ago. They soon discover the people responsible for the murders are the same yakuza wreaking havoc on the small town.
