Psychiatrist Mathias Freire and homicide squad captain Anaïs Chatelet are connected to each other through a series of crimes inspired by Greek Mythology. United in an investigation they will have to face one another and their own demons.
The body of a second man is found, tied by his hands to a burnt tree, echoing another Greek myth. But when the investigation points to a homeless man from Marseille, a shocked Mathias goes on the run.
In Marseille, Mathias is looking for his true identity among the homeless people who know him as Victor. He finds out about another murder related to Greek mythology, but Anais is hot on his heels.
Pressure mounts on Anais to abandon her investigation into the link between the murders and the stock market manipulation. Mathias's search leads him to another of his identities: painter Narcisse.
Commander Solinas asks Anais to help him solve another murder related to a Greek myth. One of Mathias's identities is linked to a clandestine speed dating night from which young women are vanishing.
As Mathias closes in on his true identity, his mother gives him a key to a safety deposit box containing information on his past. Anais walks into the lion's den but will Mathias be able to save her?
