Seventeen Lia Morel and her cousin Chris went to the city music festival, which takes place in Lyon on 21 June. After the holiday, Leah did not return home. Police investigations into her disappearance are conducted by Commissioner Molina and his young assistant, Camilla Geraine. At the same time, viewers are watching the Morel family coping with their grief. The father is trying to independently figure out what happened to his daughter. His mother supports her younger daughter, and her elder brother, Liya, suffers from feelings of guilt, because he had to accompany her sister, but she did not do that.
