Sophie's Ways(1971)

Céline is a free-spirited woman is married to a dull, middle manager Philippe. Her husband's co-worker pegged her as a household ornament because of the union. She befriends a woman who shows her how to juggle the couple's living expenses to get what she wants. As she asserts her independence and gradually frees herself from her husband's claustrophobic world, she turns to painting and writing about the inequity between genders.
