The Paris Murders - 5 ª Season

The body of a young woman is found dismembered. Her murderer took care to send all of her body parts out to addresses all over France. The victim, 22-year old Violette Grimal, was living with her younger sister Eglantine. The criminal brigade finds Eglantine alone in their apartment, giving birth. The leads to find Violette's killer are weak, especially since her sister refuses to reveal the father of her child. A mysterious man she seems to fear, and who could well be the key to the investigation. After a year-long break, Lamarck comes back to the team. Chloe settles into her new life with her little adopted daughter Lili and her mother, with whom she is reunited after 20 years of absence.

Seventy-year old Georges Vitalis abducts and attempts to kill Alice, the daughter of his future son in law, but is arrested just in the nick of time by Rocher and his team. Soon after, Natalia Volodia, a prostitute who had just arrived from the Ukraine, is found murdered in the old man's apartment. What is the link between the murder of a Ukrainian prostitute and a grandfather who is beginning to show signs of senility? The criminal brigade investigates the family of this unusual suspect and soon finds out that in many ways, his future son in law is not necessarily the good man he seems to be. The new criminologist Adele has joined the team for good, but has a tough time fitting in with her unconventional methods.

A team of journalists has been given authorization to film Rocher and his team at work on a case. When they discover the dead body of Jessica Serrano, a waitress who was hiding several thousand Euros in cash in her apartment, Chloe is surprised to run into Joseph, a autistic genius she met a few years back in a psychiatric hospital. A brilliant mathematician, Joseph is none other than the No. 1 suspect of the investigation being filmed up close and personal with our heroes.

A student opens fire for more than an hour on his fellow college students, and films the massacre on his cell phone. Rocher worries about not being able to find the crime weapon, but the end of the video shows the shooter being stopped by a professor, who then cold-bloodedly kills him with the weapon before running away. Why did this university teacher, who had already resolved the situation, suddenly turn into a murderer? Thus begins Chloe's analysis of one the most complex profiles she has ever faced. Meanwhile, Chloe meets a powerful businessman who asks her to help find his runaway daughter. Rocher continues his descent into hell with Volker, the perverse inmate who says he is willing to donate his kidney to save the life of Rocher's sister.

While Chloe meets her former professor and mentor at a criminology conference in Belle-Ile-en-Mer, Rocher is dealing with the murder of a young babysitter who was beaten to death. The investigation turns out to be much more personal than it would seem, with unexpected consequences that create tangles in Rocher's family ties. Stormy weather for Chloe as well, when the conference turns into a blood bath. Stuck on the little French island during a record storm, the criminologists are dropping like flies, and no one can figure out who the killer is.
