A short series which topic looks like a Jean Christophe Grangé's novel. A mix up between crime, thriller and horror feature. No happy ending for squeamish here, and excellent editing and screenplay where many holes remain though. What were the purposes of the rogue cops? We don't know. Frédéric Pierrot in a very surprising character for him, a rotten cop. Many surprises in this awesome French crime series, and pulled by an awesome acting too.
