Gisèle Humbert, 16, practices "Parkour" on the roofs of Paris hooded, takes off her balaclava, straps it to an aerial and continues jumping terraces until she enters one building through the roof door. Her body is found lying on the sidewalk the next day. The coroner declares it was not a suicide, for the traces of tear gas in her eyes. Investigation reveals she had been raped two years earlier by Sylvain Bontemps. Alice and Marquand discover that their first steps in street stunting coincide with the pedophile's release from prison. Only two days are left for Alice and Marquand wedding.
