Set in 1996 in a small Quebec town, 16-year-old Catherine (Kelly Depeault) navigates adolescence while her parents' marriage bitterly collapses around her. Seeking refuge from her home life, Catherine falls into a chaotic social circle of older teens, experimenting with drugs, grunge culture, and intense, messy romantic relationships. As she enters a turbulent relationship with Keven (Robin L'Houmeau) and explores emotional connections within her peer group, her journey shifts from rebellious teenage discovery to dangerous self-destruction.
