A publicity-minded French mayor reunites quintuplets and their earthy father, all six played by Fernandel.

Ten young people (six boys and four girls), most of whom students, rent a house in bad repair and set about living together. The experience is not obvious and the ten tenants have to cope with more than one difficulty. But they also have their moments. Things really go awry when Françoise, an unmarried girl, is forced to deliver the baby she carries prematurely and when Solange, the lonely girl of the group, attempts suicide. Shortly afterwards, the group learns that the house is due for demolition. They decide to take advantage of this opportunity to face adult life individually.

Josefa uncovers the ruse and refuses to help her son. However, Pierre has discovered the identity of his friend's father, who had been unknown to him for twenty years. With the help of Justin's mother, the two friends do everything they can to extort the son's missing three million centimes from his ashamed and repentant father.
