Marseille, 1962. As the Algerian War painfully draws to a close in blood and tears, the body of a man is found in the middle of the salt marshes of Camargue. Next to the body, a full jerrycan. Two cops from «L’Evêché», as the police headquarters is nicknamed, Anthureau and Molinari, are dispatched to the scene. They find that the body is that of an Arab man, and that he is exsanguinated. His blood is in the can beside him. The modus operandi is gruesome, and the murder is only the first in a series in a context where Marseille is already in the grip of extreme violence: murders, shootings, open conflicts between the OAS and the FLN, while pieds-noirs and harkis refugees are flocking in large numbers... The politicians, overwhelmed, are operating in very murky waters while local mafias are tearing each other apart to control the future French Connection. In this context, Marcel Azzara, one of their most ambitious bosses, has just had a very large shipment of morphine base stolen. However, he has files on Molinari’s sulphurous past and will therefore blackmail him to locate his drugs as quickly as possible. Over the course of these cases, in which the two investigators with opposing methods and tense relationships will discover that they are much more connected than they could have imagined, Anthureau and Molinari will each have to face their past.
