Monique Olivier: Accessory to Evil

- Season 1

(2023)

In June 2003 Belgian authorities arrest Michel Fourniret for attempted kidnapping and assault. After linking him to two other cases, they begin interrogating his wife Monique.

Letters, loneliness, and a deadly pact: with Olivier in custody psychologists analyze her history with Fourniret to understand her role in his crimes.

A prosecutor recalls Olivier and Fourniret's sheer lack of empathy as they uncovered the bodies of young women they are suspected of murdering. Later, the circumstances behind how Fourniret could afford a chateau is called into question.

When the trial opens, Olivier's role as a mother spikes public fascination and hatred. As the couple's crimes come to light, so does their sadistic sex life.

Olivier is taken out of her cell to help with a cold case in 2021 but her motives are unclear. Families of suspected victims search for answers.
