Victor, in his forties, professor of literature on vacation and amateur forecaster at Météo-France, is a will-o'-the-wisp, a sympathetic dilettante, who lets himself live with the wind, alongside his companion, Anne, who is beginning to tired of it. In this road movie in the form of a sentimental chronicle that is both burlesque and melancholy, he will tour the places of his past. He will find "what has become" of his friends. He will especially meet his former companions. They all regret it, but they all also have something to reproach him for: perhaps because they loved this being who was so amiable, dreamy, unpredictable, but above all elusive... Who knows?
