Tokyo, 1958. Teiko marries Kenichi Uhara, ten years her senior, an advertising man recommended by a go-between. After a four-day honeymoon, Kenichi vanishes. Teiko travels to the coastal and snow-bound city of Kanazawa, where Kenichi was last seen, to investigate his disappearance. When Kenichi's brother comes to help her, he is murdered, poisoned in his hotel room.

Soon, Teiko discovers that her husband's disappearance is tied up with the so-called "pan-pan girls", women who worked as prostitutes catering to American GIs after the war. Now, ten years later, as the country is recovering, there are those who are willing to take extreme measures to hide that past.
