Pascal Jagot receives an anonymous email and tasks Nadia with reopening a file closed four years earlier. This was an accident involving a hit-and-run which did not give rise to any judicial investigation. Nadia exhumes the body of the victim, Nathalie, and the results of the autopsy are damning: she was indeed murdered. At the same time Rovère investigates the murder of a taxi driver. Very quickly, they realize that the two cases are linked... A second murder, that of a fashion photographer with a scandalous reputation, occurs. Nadia and Rovère will have to reconstruct the evening where Nathalie died and prevent the killer from continuing to kill his alleged assassins. (thetvdb.com)
