A woman and her daughter are raped and murdered by soldiers during a time of civil war. Afterwards, a series of samurai returning from the war through that area are found mysteriously dead with their throats torn out. The governor calls in a wild and fierce young hero, to quell what is evidently a ghost. He encounters the two beautiful women, in an eery, beautiful scene. After spiritual purification, he meets the demon in a thrilling fight.

In 12th-century Japan a woman and her 20-year-old daughter-in-law are raped and then slain by a band of samurai. Their hut is burned, and their blood attracts a black cat. Later the leader of the samurai band returns to the area and is mauled to death by a seductive woman who resembles his victim. Another samurai band, led by Raiko, comes to the area. Gintoki, the husband of the murdered young woman and the son of the older woman, is a member of this band, and Raiko orders him to get rid of the ghosts who have been preying on the samurai. Gintoki meets the spirit of his dead wife, and she takes him back to a hut where he also sees the spirit of his dead mother. The two women vanish, but the next day the young woman returns to her husband; despite her vow to murder the samurai, she and her husband make love and remain together for 7 days. She is banished from the spirits of hell, however, in return for her husband's life. Raiko again orders Gintoki to destroy the apparitions, and the next time he encounters his mother, Gintoki severs her arm. That night, the mother returns for the arm, and the next morning Gintoki lies dead as a black cat licks his wounds.
