Requiem pour un caïd (1964)

Police officer Antoine Delille is in charge of putting an end to the activities of a "kingpin", Jo Pinelli, trafficker, racketeer and pimp. He has three women working for him, including Eva and Jeannette, and is currently "conditioning" a charming, naive Orly employee, with whom he poses as an honorable businessman. Inspector Delille's plan is to arrest Jo for some crime and, while he's being held at the P.J., to delve into his other criminal activities and confound him.
