A melodrama about the life of a mentally disabled young man and his devoted sister after their famous novelist father and housewife mother go to Australia on a business trip.

Older, wiser but still a wandering loner, the blind, peace-loving masseur Ichi seeks a peaceful life in a rural village. When he's caught in the middle of a power struggle between two rival Yakuza clans, his reputation as a deadly defender of the innocent is put to the ultimate test in a series of sword-slashing showdowns.

The film stars two of Itami's regular actors, Nobuko Miyamoto as a geisha who brings luck to the men with whom she sleeps, and Masahiko Tsugawa as her unfaithful, sometimes partner. As well as showing her relationships with the man she loves and the men who employ her, it satirizes corruption and the influence of money in Japanese politics.
