La Fille Prodigue The Prodigal Daughter (1981)

Anne (Jane Birkin) is a seriously disturbed young woman who is driven to leave her husband for awhile and go home to her parents in the countryside. Once there, she comes up against many of the primal causes of her own imbalanced mind. Her father is in an indecisive relationship with both his wife (Natasha Parry) and his mistress (Eva Rensi), and does not seem a pillar of stability himself. When Anne confronts her father, their relationship degenerates, leaving little promise for the future.
