In war-torn 16th-century Japan, two ambitious peasant families struggle to improve their lives but get caught in the turmoil of conflict and personal desires. Genjuro, a potter, dreams of making a fortune by selling his wares in a larger market, while his brother-in-law, Tobei, yearns to become a respected samurai. Despite warnings from their wives, Miyagi and Ohama, the two men decide to pursue their aspirations. Genjuro travels to a nearby town with his pottery and encounters Lady Wakasa, a mysterious noblewoman who shows great interest in his work, leading to a relationship that tempts him away from his family. Tobei, after stealing a suit of samurai armor, finally gets the recognition he craves but at a great personal cost.

Ohama is left alone and is subjected to hardships in her quest to find Tobei. The story intertwines themes of ambition, love, and the supernatural, highlighting the fragility of human desires amidst the chaos of war. Ultimately, the choices made by Genjuro and Tobei bring unforeseen consequences that deeply affect their lives and the lives of their loved ones.
