Stéphane Petitbourgeois is having trouble with his son-in-law Hubert, who has an extra child every year and is expecting his ninth, making thirteen people in the same apartment. However, a competition promises twenty million to the youngest grandfather of twelve grandchildren. Stéphane begins to encourage Hubert. But Pat became sterile from that day on. Finally, after two years, a child is announced. In fact, triplets were born, and after a few twists and turns, Stéphane became the youngest grandfather of twelve grandchildren.
