The three siblings gathered in the countryside to celebrate their mother Hélène's (Edith Scob) 75th birthday. The three generations of the family were full of joy. After dinner, the mother mentioned to her eldest son Frédéric (Charles Berling) how to deal with the inheritance after her death. Frédéric was a little annoyed and didn't want his mother to bring up the topic. However, Hélène insisted on arranging the whereabouts of all the items. She told her son that the ancestral house would be sold, and what about the paintings of her uncle, the painter Paul, whom she respected all her life, etc. Frédéric insisted that the house would be preserved and left to the children to pass on. A few months later, Hélène passed away. Frédéric, who had been living and working in Paris, hoped to keep the ancestral house. However, his younger brother Jérémie (Jérémie Rénier), who was about to move his family to China for work, and his younger sister Adrienne (Juliette Binoche), who was about to go to New York to get married and start a family, agreed to sell the ancestral house because they would never return to Paris. Everything was just as his mother said. Frédéric reluctantly accepted and set about dealing with things. In the last month of the house's sale, Frédéric's children held a grand party in the ancestral house, where youth was staged, and the inheritance of the feelings of the ancestors might continue in another way.
