A happy couple with many children, Claude and Maria Vernay, are raising four beautiful daughters. They are true Catholics who represent an old France. They are respected in society, as they have a good job, four children and a big house. The parents did not expect that their three daughters would find husbands so quickly and get married. The only thing that confuses them is their sons-in-law, who are a little different from them: a Jew, a Chinese and an Arab. For parents, this is a serious problem. Their only hope is for their last daughter. Soon they learn the good news, their fourth daughter marries a true Catholic. But it turns out that the groom is a black West African from the Ivory Coast.
