Dolls

A police car is chasing crooked dealers in the Provençal countryside. He arrives at an abandoned, half-demolished chapel, which surprisingly has a brand new castle on it. The intense smell that is spreading around gives the impression that a heinous crime has taken place. Inside, detectives find six mutilated corpses in various stages of decomposition.
The brutal case is entrusted to the respected Commissioner Venturi, known as the Cowboy. This gives him a chance to redeem himself from the conflict with the Inspector General, which is currently conducting disciplinary proceedings against him. Venturi calls in a psychologist to investigate, who turns out to be a young and talented criminologist Olivia Montalvert, affectionately nicknamed Mentholka. Despite the initial distrust of the experienced policeman towards the newly graduated girl, the two become a well-matched tandem.
The interplay of police experience and female intuition will be a necessary condition for success, since the perpetrator is a mentally disturbed person. Considering the state of the bodies, which the killer had perfectly shaved and dressed up, it can be concluded that he plays with his victims like dolls. And he'll keep killing until the CSIs stop him.
