Following the massacre of many thousands of Christians by soldiers of the Tokugawa Empire after the Shimabara Rebellion, Shiro Amakusa renounces the God who he feels abandoned them, and bargains his soul to the forces of darkness for the power to take his revenge. He gains the power to resurrect the dead, and begins with Hosokawa, the wife of a samurai who mocked her for her chastity and then left her to die during the invasion. Shiro restores her beauty in exchange for her loyalty. Next, they travel to the cave of legendary swordsman Miyamoto Musashi, who regrets that he neglected his lovely wife to find more opponents to duel, and that his advanced age prevents him from challenging the one rival he considered worthy to test his technique. He initially resists the pair, but suffers a heart attack and agrees to join them. During this exchange, his cave is visited by Yagyu Jubei, son of a samurai master and a powerful swordsman in his own right. Jubei rushes to Musashi's aid only to find an empty suit of armor. The unholy trio then encounter Inshun, a Buddhist monk who is plagued with terrible fantasies of sex and death. Hosokawa taunts him with the failings of his monastic teachings, and he commits suicide in despair, becoming one of Shiro's undead in the process.

Nine young samurai, including his nephew, believe that the lord chamberlain, Mutsuta, is corrupt after he tore up their petition against organised crime and said maybe he himself was behind the crimes. One of them tells the superintendent of this and he agrees to intervene. As the nine meet secretly at a shrine and discuss their problem, a ronin (Mifune) emerges from another room where he has been resting. The ronin has overheard their plans, and suggests that the superintendent is in fact the real corrupt official. While at first the samurai are insulted by his claims, they soon find themselves surrounded by the superintendent's men, proving that he was correct. The ronin hits a few of the attackers and bluffs their leader into leaving, taking only a small amount of money in reward to buy food because he is starving; however, after realizing that Mutsuta and his family must now be in danger, he decides to help the samurai bring down the corrupt officials.

The story of the Forty-seven Ronin has been depicted in many ways, with each version focusing the emphasis on different parts of the story—the rivalry of Lords Asano and Kira, Asano's assault on Kira, Asano's sentence of seppuku immediately afterward, and the revenge attack 21 months later against Kira by the Forty-seven Loyal Retainers. Oishi Kuranosuke, Asano's chamberlain and the head of the 47 samurai, is often the primary character, and his actions are often held up as the epitome of bushido, the honor code of the samurai.
