Les Ombres Rouges - Season 1 (2019)

Aurore Garnier, a police officer, has been obsessed with the abduction of her 5-year-old sister Clara. Their mother, Isabelle, died while handing over the ransom. 20 years later, their grandparents are about to sell the family estate.

Clara shows up at the estate and introduces herself to Paul, her grandad. Paul and Aurore are convinced of her identity, while brothers Fred and Gabriel are skeptical. Gabriel's nightclub is burned down.

Now officially a Garnier, Clara has a say in the sale of the estate. What if her birth father abducted her and killed her mother? Could it be Ivaldi, the man who raised Clara in Italy? Aurore manages to find DNA at Ivaldi's house.
