Natalie (Isabelle Huppert) is a philosophy teacher who has been married to her husband Hans (André Marcon) for decades. They have raised two children together and have a peaceful and happy life. One day, Hans suddenly confessed to Natalie that he had a lover outside. Not only that, he also planned to move out of the house and live with his lover. Although Natalie pretended to be calm on the surface, she suffered a strong blow in her heart. Natalie's mother (Edith Scob) was once a popular model, but now she suffers from depression and has attempted suicide many times. In desperation, Natalie had to go against her mother's wishes and send her to a nursing home. At the same time, Natalie followed the advice of her former student Fabian (Roman Kolinka) to go to the commune established by Fabian and his friends in the mountains.
