Claude (Christian Clavier) and Maria (Chantal Lauby) have been married for many years and have a very good relationship. They have four daughters, Isabella (Frédérique Bel), Odile (Julia Piaton), Ceglia (Emilie Caen) and Laura (Elodie Fontan). In the blink of an eye, the four beautiful sisters have grown up and reached the age of marriage. Claude and Maria are devout Catholics. Of course, they hope that their son-in-law can have the same faith as themselves. However, the reality is often not satisfactory. The first three daughters fell in love with Arabs, Jews and Chinese respectively. The old couple placed their last hope on their youngest daughter. What they didn't expect was that the youngest daughter led an African-American man to stand in front of them.
