A young couple goes to a hospital after hearing rumors of a demonic spirit known as the Slit-Mouthed Woman. Inside, they are overcome with a powerful desire for sex and hide in a room to indulge. There, they are confronted by a grotesque, disfigured woman emerging from the shadows. *The Slit-Mouthed Woman*, by controversial director Takuaki Hashiguchi (known for *Woman Prisoner Torture*), blends eroticism and horror. The film features impressive special effects by Takashi Oda, who previously worked with Beat Takeshi Kitano on *Sonatine*.
