Since their divorce 29 years ago, Jacques Berthier and Francine Blanchard have seen little. They meet again today, while Jacques receives a badge of honor to mark his work at the Mémoires Vives Foundation as an extremely dynamic organization helping the relatives of missing persons, of whom they are the founders. Despite their differences, Jacques and Francine are united by a common drama, the disappearance of their little daughter Laurie thirty years ago. Although Jacques never lost hope of finding Laurie one day, Francine saw this disappearance differently. Would she have something to hide? The second wife of Jacques, Claire Hamelin, also carries a moving secret that will soon burst open. For the past three years, Claire has lived alone in the family home of Saint-Hilaire, where Jacques and she, very much in love with each other, have raised their two daughters, Flavie and Mathilde.
