Meet the Morvan family: the father heads the French police, the eldest son follows in his father’s footsteps, the youngest is a successful financier and long-time drug addict, the daughter is an unsuccessful actress—but finds success as an escort girl. The family members are tightly bound to one another—especially tightly because their mutual hatred unites them. But then in France a series of strange murders begins, strikingly similar to those committed by the famous serial killer nicknamed the Nail-Man in the 1970s in Congo. Yet the Morvan father long ago solved those old crimes. So who is operating in France—and why do the blows fall on the family of the number one police officer?! Will the Morvans manage to withstand the attacks of an unknown enemy, or will they become victims of their own passions?..
