Nadine Dutertre has just been murdered. She was marketing director of the Kauffmann laboratory. The investigation focuses on Nathalie Faubert, head of the "Mères En Colères" collective, who is up in arms against the Metatron that the lab sells. According to her, this molecule against epilepsy is the cause of their children's physical malformations, and even for some of them autistic disorders.
