Eliane is called upon to shed light on what prompted Pascale to poison her two children. While Madeleine, 7 years old, is between life and death, Henry, 4 years old, could not be saved. Did Pascale act in cold blood or was she in a psychotic state at the time of the tragedy? In order to understand what really happened, Eliane teamed up with her faithful collaborator, Boisvert, as well as with the fearsome defence lawyer, Michelle Simon.

Now medicated against her will, Pascale has withdrawn and refuses to eat; Éliane contacts a former patient to help her break through her shell. As little Henri's funeral approaches, tensions rise within her family. Pascale's biological mother explains the reasons that led her to give her up for adoption. Camille receives surprising confidences from Madeleine. While trying to learn more about Shanny, Boisvert makes a surprising discovery.
