Christopher (Billy Drago), a Victorian era American journalist, is traveling through Japan looking for Komomo (ItÃ´), a lost girlfriend whom he had promised to rescue from prostitution and bring to America. Landing on an island populated solely by whores and their masters, he is solicited by a syphilitic tout (Yamada). He claims no knowledge of Komomo, but Christopher has to spend the night, requesting the company of a girl (Youki Kudoh) lurking back in the shadows, who joins him in his room.Disfigured and disturbed, the girl claims a closer connection with the dead than the living. She tells him that Komomo was there, but hung herself after her love never came for her. Distraught, Christopher seeks solace in sake. Falling asleep, he requests a bedtime story. The girl recounts her past â her mother, a midwife, was forced to sell her to a brothel after her father died, and eventually she wound up on the island. Komomo was the most popular girl there, making the others jealous. When the Madam's jade ring was stolen, Komomo was tortured to confess. After suffering hideously â underarms burned, needles driven under fingernails and into gums â she hung herself in torment and tired of waiting for her love.Christopher refuses to believe the girl's story, and he pleads for the whole truth. The girl starts again, in the second telling, her family is no longer happy nor loving; her father was an alcoholic, her mother an abortionist. She was taken in by a Buddhist priest, who, presumably, molested her and inspired an obsession with hell. Her father never died of lung disease â she beat him to death for raping her. Again she tells of being sold into prostitution, but gives a new version of the dark fate of Christopher's beloved Komomo. Despite the kindness of Komomo, who befriended her, the disfigured girl stole the jade ring and planted Komomo's hairpin to frame her â and after Komomo was tortured, killed her. She explains to Christopher that she intended to save Komomo from hell: as Komomo would be doomed for having such an evil friend, only through betrayal could she sever the friendship and ensure Komomo a deservedly beautiful afterlife.Christopher, losing control, is desperately convinced something has been left out. He begs for the whole truth. The woman then reveals a horrifying secret: a tiny second head in the center of a hand hidden beneath her hair â her "Little Sis", a parasitic twin. Her mother and father had been brother and sister, "Little Sis" was the fruit of their incest. It was "Little Sis" who commanded her to kill her father, and to steal the ring. As the hand begins to talk like Komomo in a high-pitched voice, Christopher is overcome by madness and threatens to shoot her and send her to hell. She informs him that wherever he goes, he will be in hell - a flashback implies that he was responsible for his sister's death. He shoots the girl in the heart and then the head. Before dying, the girl's body turns into Komomo.The epilogue finds Christopher in a Japanese prison serving time for the murder of the girl. When he is given a water ration, he hallucinates the bucket contains an aborted fetus, and cradles the bucket while singing a lullaby, kept company only by the ghosts of Komomo and his dead sister.
