Comte de Larzac, an aging seducer, leaves Paris for Lannemezan. Accompanied by his friend Charmeuil, he goes there to acknowledge the paternity of Jean, a twenty-year old young man who knows nothing about his biological father. Jean, after falling for Jeanne, the daughter of a farmer, now courts Georgina, a middle-class woman of Romanian origin. After Father Jocasse has told Jean that he is Comte de Larzac's son, the young man follows his father to Paris. But he finds it hard to comply with the usages of high society and when his father refuses to consent to his marriage with Georgina, he returns to Lannemezan. Georgina is so upset by the count's refusal that she comes to see him and tells him very candidly about her past life. Moved by her plea, de Larzac drives her back to Lannemezan so that she can marry Jean. What was not expected is that, during the trip, they discover they are close to each other.
