Magistrate Mayuzumi

A nameless ronin, or samurai with no master, enters a small village in feudal Japan where two rival businessmen are struggling for control of the local gambling trade. Taking the name Sanjuro Kuwabatake, the ronin convinces both silk merchant Tazaemon and sake merchant Tokuemon to hire him as a personal bodyguard, then artfully sets in motion a full-scale gang war between the two ambitious and unscrupulous men.

The Shogun sentences Asano to seppuku and deprives the palace and lands from his clan, but does not punish Kira. Asano's vassals leave the land and his samurais become ronin and want to seek revenge against the Lord's dishonour. But their leader Kuranosuke Oishi seeks to restore the Asano clan with his brother Daigaku Asano. One year later, the Shogun refuses, and Oishi and 46 rōnin are out for revenge.
