Les Témoins - Season 2

A police lieutenant in northern France is assigned to investigate the grim discovery of 15 frozen bodies, sitting on board an abandoned bus, on the first day of spring. All 15 men were at one time or another involved with a woman named Catherine Keemer, but she disappeared three years earlier.

The police investigating team begin to understand the murderer's modus operandi, and Sandra becomes increasingly sure Catherine holds the key to the mystery. Meanwhile, someone else steps forward claiming to know who the killer is.

The body of a young woman is found buried under a wind turbine, and police try to figure out whether her death is related to the other murders. Meanwhile, Sandra starts using the same dating app Catherine used prior to her abduction, and it becomes ever clearer that she has become personally involved in the investigation.

Catherine holds Martin Souriau captive, believing him to be the kidnapper, and she resolves to do whatever it takes to save her child. Meanwhile, Sandra realises she is beginning to fall for Antoine, even though he could be the person who broke into her apartment.

Antoine's car is found in the middle of a forest, but the driver is no-where to be seen. Meanwhile, Sandra remains on the run with Catherine, and the pair try to figure out who Martin Souriau is covering for as they pursue the killer - and Catherine's missing baby.

Sandra discovers a new line of inquiry as she investigates the Mount St Michel orphanage, and finds a group photograph of the children who once lived there. Convinced that the key to finding the killer lies in within this old picture, she resolves to track down everyone seen in the portrait.

Sandra finds herself in the clutches of the killer, who intends to subject both her - and her past lovers - to the same grisly fate that awaited his previous victims. Meanwhile, Audrey Solange's refusal to talk causes Justine and Max's investigation to stall, prompting Catherine to make some enquiries of her own.

Sandra tries to find a way to escape from the killer before she can become his next `bride', but the wellbeing of her past lovers remains unknown. Catherine continues to search for her baby, and the mystery of the power `the Minotaur' held over the children of the Mount St Michel orphanage is revealed.
