Vortex 1x2

After discovering that Zoé Levy and Mélanie were wearing the same ring when they died, Ludovic is now certain that they were murdered by the same person. Are there other victims that no one has linked to this case so far? At the same time, Mélanie's changed actions in 1998 have devastating consequences for the future: colleagues and friends do not meet. Their current family simply does not exist. These changes cause Ludovic to panic. What happens if Melanie survives... what will happen to Parvana and Sam then?
