Returning to their lord's castle, samurai warriors Washizu and Miki are waylaid by a spirit who predicts their futures. When the first part of the spirit's prophecy comes true, Washizu's scheming wife, Asaji, presses him to speed up the rest of the spirit's prophecy by murdering his lord and usurping his place. Director Akira Kurosawa's resetting of William Shakespeare's "Macbeth" in feudal Japan is one of his most acclaimed films.

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.
