A Criminal Affair

Laurence Malenfant, a young policewoman, shoots a witness who made an important revelation about the disappearance of her father, an ex-investigator.

The BEI discovers that the man who was shot by Laurence during the police intervention had a compromising video in his possession.

Laurence and Geneviève have reason to believe that Philippe has information about the disappearance of Jean-Claude Malenfant.

Although the BEI has accumulated a great deal of evidence, new information muddies their waters and the course of the investigation.

The victims found on Île Notre-Dame have two things in common, being police officers and leaving suicide notes after their disappearance.

With the media aware of the circumstances surrounding Poupart's death, Laurence fears that her name will be dragged through the mud; as new evidence incriminates Poupart further, Corbeil discovers Philippe Laberge's dark secret.

Laurence's meeting with a high-ranking G.R.A.P. executive shuffles the list of potential serial killers; a suspect is taken into custody and interrogated by Geneviève for several hours.

The hunt for the murderer continues, and the faces of the culprits are revealed; the truth creates a shakeup in the lives of Laurence and Geneviève; at a crossroads, the two women must make heartbreaking decisions.
