Widowed five years earlier, she juggles work as a translator with raising her eight-year-old daughter and looking after her father, who has a neurodegenerative condition that is causing blindness and delusions. As she struggles to find a suitable care facility for him, Sandra runs into an old friend of her husband’s, the unhappily married Clément, and begins to let go of her past.
