-Brigitte Francoeur returns to her hometown, Sainte-Alice-de-Rimouski (in Quebec, Canada), for her daughter Jade's wedding. The latter, who is 20 years old, was raised by Noémie, Brigitte's older sister and her husband. Noémie is also the director of the Centre Jeunesse L'Échappée. On the wedding day, Claudie Lyndsay, 14, and Greg Laplante, 16, ran away from the Centre. A few hours later, Agnes, one of their educators and Brigitte's childhood friend, was the victim of a terrible attack. The first suspicion is on Patrick Landry, Agnes' former partner, a man who has difficulty controlling his aggressiveness, and on the two runaways. Buried secrets then resurface. We discover that this small idyllic community, where everyone knows everyone, has an immense talent for keeping up appearances. The investigation to discover Agnes' aggressor may upset the small community in its foundations.
