When you're a cop in Marseilles, threats of violence and revenge go with the territory. Usually they come to nothing, but when friends and colleagues start turning up dead it soon becomes clear that someone from Jacquot's past has a score to settle and intends to see it through. But this killer is different. To sweeten the revenge, and cause the greatest pain, it's always the target's nearest and dearest who die. When Jacquot discovers that he's in the firing line, he knows that unless he can track down the killer then someone he loves will pay the ultimate price.
