Then out of the darkness a perverse and disfigured woman appears and confronts them.The Slit-Mouthed Woman, a.k.a Kuchisake, is an original hybrid of pink erotica and horror from the controversial J-sploitation director Takuaki Hashiguchi whose previous films include the disturbingly nasty Woman Prisoner Torture.
