While Laure Berthaud's group has been shattered, a double homicide in a Chinese restaurant in Belleville will bring together the Laure-Gilou tandem. What appears to be a simple heist gone bad turns out to be a complex affair that will lead the group to investigate hidden financial networks. Our characters will be confronted with unexpected obstacles, drawn up by their own hierarchy. This time, small arrangements with procedure will not be enough and they will be faced with a dilemma that everyone will have to manage in their own way: to renounce the truth or to betray the institution they have always served.
