Intimidade (1975)

Tanya is a top model married to Roberto, head of an advertising agency, who runs it with his twin Alex. They are doing business with an industrialist and his assistant Pedro. Roberto, Alex and their buddies go to a striptease and they lie to Tanya to cover themselves. Tanya feels consumed by the stifling, oppressive celebrity machine and tires of Roberto's controlling nature and being exploited further as a sex object, so she runs away to a small town and meets a hippie painter named Cicero, to whom she feels magically attracted. They have an affair, but his unpredictable temperament soon disillusions her, and she feels everything is useless, leaves again and moves on alone.
