Yet they plan and carry out the murder of an unknown woman they have previously only spotted on the street. The police are at a loss, confused by this murder without motive. Zoé, an optician in the neighborhood, who is feeling more and more moved by this inexplicable murder, bumps into the teenage murderers by chance. But this chance fleeting encounter reveals inside her a growing and mysterious desire. Although scared (she could easily be a victim of Damien and Pierre), her erotic attraction for the duo goes beyond that. It gives her a chance to find a way out of the loveless rut that her life has ended up in. While Damien and Pierre, thinking no one will catch them, embark on a journey deep within their pasts.
