At 55, Anne is finally enjoying her freedom after her children leave home. But everything changes when her 23-year-old daughter, Louise, moves back in with her after a professional and romantic failure. And to make matters worse, her son, Théo, announces that she's going to be a grandmother! Anne realizes that life never goes as planned and that, at any age, we are still learning to grow up.
