La collectionneuse (1967) Eric Rohmer

The arrogant and pretentious intellectual art dealer Adrien invites his girlfriend to travel with him to the coast to spend one-month vacation with his close friend and painter Daniel in the house of their Randolphe. Adrien expects to do nothing but read and rest in the house, and meet a possible investor in an art gallery that he dreams on having; however, she prefers to travel to London. When he arrives, he discovers that the sexy and promiscuous pleasure-seeking Haydee, who had a one-night stand with Randolphe, is sharing the house with Daniel. Among the days, Adrien becomes obsessed in a sick game of humiliating Haydee and imaging that she is trying to seduce him; however, his lust for her increases but his moral rationalization of their possible relationship keeps them apart.
