Gaby (Agathe Natanson Marielle) and Jo (Bernard Farcy) are an elderly couple without children, living alone in their flat. Throughout their lifetime, they each had life plans and yet never managed to live out their dreams and Gaby felt a deep sense of guilt and trauma due to her inability to conceive children.

As Jo approaches the end of his life, his memory slowly fades away. Gaby sees a chance to give her husband a taste of the life he had never lived. Every night while he sleeps, she places false memories all over their apartment: fake trinkets and family photos filled with grandchildren.

Since she can no longer rely on the future to change things, she will try to change the past to give Jo the feeling of a fulfilled life with no regrets.
