The Robinards form a family divided into two irreconcilable clans: the Léonce branch and the Sébastien branch. That day, the village of Boissy-sous-Saint-Yon was abuzz with activity: at the cemetery, the grandfather, Sébastien Robinard, was buried. At the same time, Marcel Robinard, a descendant of Léonce, was getting married in church. Not to mention a bicycle race and a parade. All these events collide.
