Lisa Pouvray, 15, packs her backpack, kisses her father Jérôme, who works nights, goodnight and goes to bed. Later that night, she is in the streets, dressed in shorts, fishnet stockings, hair in a bun, searching for a pharmacy. She complains about a pain in her abdomen but passes out in front of the pharmacist who finds out she has blood on her right side and calls an ambulance. The coroner declares cause of death a gunshot. Lisa had morphine in her blood and signs of recent sexual activity. At the lycée, Marquand and Alice discover she was a model student, but not popular, only friend Thibault Gauthier. They are shocked to know she spent her nights at parties in abandoned houses.
