During the violent chaos of post-War Japanese black market, a young gangster called Shozo Hirono has to keep up with the rapid shifts of power between unscrupulous bosses.

After being wounded in a fight, Zatoichi is nursed to health by a young woman and her father. Now indebted to the family, he works to protect their ferry business from local thugs.

Conflicts between Hirono's family and Yamamori's family (and their allies) are made more tense by the ambitious underlings and the police's efforts to impose a crackdown on the gangs.

A former soldier, reduced to working at a restaurant post-war, becomes a contract killer for the yakuza gangs he's in contact with.
