The Lie (1985)

This is a story of love and lust shaded with overtones of incest and lesbianism. Livia is a woman trying to regain the affections of her husband Alberto, whose journalism career takes him away for months at a time - on purpose. What she does not know is that he has an undeniable attraction for their daughter Monica. Livia's own sexual eccentricities lead her to hire young women to have sex with Alberto while she listens in hiding. When Monica wants to get into the act too, the real truth about her parentage is revealed.
