Now irrelevant in this 2.0 company, Jean-Claude is fired! Hervé is charged by the management to make Jean-Claude clear off quickly and without a scene. In doing so, they will tear down their memories, mixing the great and the small history of the past 20 years. Over the course of these memories, Hervé and Jean-Claude will renew the bonds of a lost friendship.

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.
