Thriller told from the perspective of a young forensic artist, Éve, who creates profiles of suspects and victims for a police unit in Montreal. She suffers from bipolar disorder, but is very good at her job: she is able to "read" people, as it were. When her ex returns, she is forced to re-open the case of her son's disappearance with the investigative team. What follows is an insight into the ins and outs of a rather uniquely composed detective team.
