The third installment of the “Law & Order” franchise takes viewers deep into the minds of its criminals while following the intense psychological approaches the Major Case Squad uses to solve its crimes.

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.

In cases ripped from the headlines, police investigate serious and often deadly crimes, weighing the evidence and questioning the suspects until someone is taken into custody. The district attorney's office then builds a case to convict the perpetrator by proving the person guilty beyond a reasonable doubt. Working together, these expert teams navigate all sides of the complex criminal justice system to make New York a safer place.
