Villefranche is a small town isolated in the heart of a gigantic forest, a green labyrinth of thousands of hectares making any telecommunication hazardous. This unusual place has uncharted areas, crimes, disappearances and other mysteries to solve, as well as a homicide rate six times the national average. But other than that, everything is fine. To watch over her, the town can count on its “sheriff”, Major Laurène Weiss, a local girl with a strong mouth and a strange connection to nature.
As her investigations progress, Laurène Weiss goes deeper and deeper into the trees to uncover their secrets, especially and first of all that of her own kidnapping twenty years earlier.
