HPI - Season 4

Morgane is pregnant again. Karadec is also a possible father. Her children are urging her to have an abortion, but she is not yet sure whether this is an option for her. At the same time, Alexandra Collet, 42, a housewife with a hearing-impaired son, is found dead by her husband.

Morgane's pregnancy coincidentally leads her directly to the next crime scene, where an artificial insemination specialist is found murdered. Dr. Bubé was killed with a fire extinguisher in his office.

While her children force her to contact the potential fathers of her child, Morgane is called to new investigations: Antoine Broussin, 85 years old, author of crime novels, is found dead in a secret room of his house.

Fred is absent for at least six weeks and the homicide squad is now provisionally headed by Celine. In a fateful twist of fate, Karadec's old team and his new team meet over the same case.

In the Cathy Barriot death case, Morgane notices that bath balls that have fallen on the floor tend to be evenly distributed. It looks as if someone had put them there on purpose. Which means it must not be an accident, but murder.

Celine is given permission to reopen the Emma Perrin case. A seven-point ladybug stuck to Emma's windshield reveals to Morgane that she must be in Brittany. There, she and Karadec meet a survival troop.

Morgane is preoccupied by the death of influencer Wendy. Wendy's death seems to be linked to her desire to see her once abandoned child Alma again.

The case of the strangled Dr. Guillot, whose colleague Dr. Xavier Decker is suspected by Morgane from the outset, is a headache. The time of death can only have been during the period for which Dr. Decker has a solid alibi.
