Eight years after the brutal murder of his wife Margot (Marie-Josée Croze), pediatrician Alexandre Beck (François Cluzet) is still haunted by the life they lost together. When two bodies surface near the original crime scene, the police reopen the investigation, and Alex suddenly finds himself back in their crosshairs.

As Alex is thrust into a deadly maze of secrets, lies, and long-buried conspiracies, he must outrun both the law and the shadows pursuing him. What if the truth isn’t dead… and neither is she?
