Magobei Wakizaka is a samurai for the Sabai clan. A nearby island, Sado, boasts a rich gold mine which provides plentiful riches for the Tokugawa clan. When one of the gold ships sink, the local farmers recover some of the gold, intending to return it to the Tokugawa clan. However, Magobei's clan master, Rokugo Tatewaki, takes the gold and slaughters the farmers so they cannot report the gold stolen. Magobei is appalled. He promises not to report Rokugo to the shogunate in exchange for Rokugo 's promise to never do so again.
However, three years later, assassins sent by Rokugo's retainer, Kunai, come for Magobei, who is living in Edo. He realizes that Rokugo intends to steal more gold and slaughter more innocents. So Magobei returns to Sabai to face his former master. Rokugo hires another ronin, Samon Fujimaki, to kill Magobei, but Magobei eventually wins him over. Also, along the way, Magobei meets a young woman, Oriha, who survived the original slaughter. She and her brother, Rokuzo, join him on his way to Sabai.
At Sabai they learn that Rokugo intends to move a bonfire, which serves as a warning to passing ships against dangerous rocks, so that a gold ship will hit the rocks and sink. After recovering the gold, Rokugo intends to slaughter the peasants who help him in this endeavor. The combined efforts of Magobei, Samon, Oriha, and Rokuzo result in the correct bonfire being lit, the fake bonfire being put out, and the innocent peasants' lives being saved. Thus the gold-bearing ship evades the rocks. In a final showdown, amid falling snow, Magobei slays Rokugo, but is wounded by one of Rokugo 's throwing knives.
