Unfaithful Wife: Shameful Torture (1992)

Surreal, semi-pornographic fantasy in the "pink cinema" genre, exploring serious themes of voyeurism, alienation and perversion. Former actress Kyoko is miserable in her cold marriage, ignored by her lover, and obsessed with filming and being filmed. The boundaries of real and imagined are blurred more and more as she starts experimenting with the impersonal sexual rituals and hallucinogenic drug that may have killed her sister.
