In the Nineteenth Century, the acupuncturist Soetsu lives with his daughters Oshiga and Osano in the Shimousa Province, Japan. He saves some money, becomes a moneylender and lends his money to the samurai Fukami. Three years later, he visits Fukami to collect his money and the samurai kills him and dumps his body in the Kasane Swamp, where bodies disappear and never return to the surface. However, before dying, Soetsu curses Fukami and the samurai goes crazy and kills his wife. Twenty-five years later, Fukami's son Shinkichi, who is a street vendor of tobacco, meets Oshiga, who is a singing teacher in Edo, and they fall in love with each other. Oshiga is older than Shinkichi and financially supports him. She becomes infamous in Edo and when her student Ohisa flirts with Shikichi, she becomes jealous and decides to give no more classes to her. Shinkichi decides to leave Oshiga and move to his homeland Hanyu with Ohisa. Oshiga has an argument with Shinkichi and he hits her face with the Bachi of her Shamisen. Oshiga has an infection in her face and dies; however, she curses Shinkichi and promises that she will haunt and take to the grave any woman that he loves.
