Sid Ahmed Rezala, a Hell of a train (5x2)

Air date: Sep 21, 2024

1999, a year of terror on the trains. A young woman is savagely thrown out of a window during a Limoges-Paris journey. Then, a mother is murdered just a few meters away from her child on the Calais-Ventimiglia night train. A suspect with a particularly disturbing profile, three different police services mobilized, an international manhunt, and an investigation that will eventually lead to Portugal.
