Antoine, 17, points a hunting rifle at his father in their living room and pulls the trigger. His father dies instantly; Antoine thought the gun was unloaded.

Clélia realizes that Antoine might be lying to protect his mother. To understand why, Clélia must delve into the twists and turns of the Durands, an ordinary family built on a foundation of violence, racism, and exclusion, where evil deeds have been repeatedly committed for generations.
