While Mathilde and Ghemara are on Reunion Island on holidays, Jocelyn Tibao, an attractive young man, tries to approach Mathilde. The next day, Ghemara finds both in car and starts following them. Unfortunately they're involved in an accident and the car plunges into the ocean; Tibao dies but Mathilde survives, seriously injured. In Bordeaux, the SR links this case and the unsolved murder of Jenna Payet occurred in Bordeaux three years earlier, and they all fly to Reunion to join Ghemara.
