Tunisian-Jewish businessman Alain Berrebi (Michel Boujenah) courts Ashkenazi princess Arlette Stern (Elsa Zylberstein). Her father David (Maurice Chevit) learns of the death of a rural Auvergne peasant who once hid David and his cousin Nathan (Felix Fibich) from the Nazis. Nathan is now a NYC diamond dealer on West 47th Street. David, Nathan, Arlette, and Berrebi head for the funeral in Auvergne. There they encounter the deceased peasant's son, Jean Bourdalou (Gerard Depardieu), who operates the family's restaurants in Paris. Arlette does a romantic take on Bourdalou, which sends the distraught Berrebi off to cry on the shoulder of his mother Gaby (Gina Lollobrigida). Back in Paris, Bourdalou and Berrebi make plans to open a trendy fashion restaurant in Manhattan.
