The Whistlers

Lila has disappeared. On her social media page @lessiffleurs, she posted photos of men who harassed her. Appointed to head the investigation Marianne, finds herself up against an unexpected problem: the father of Solène, friend of the victim, turns out to be the man who raped her twenty years ago.

Lenoir discovers photographs of Solène on porn websites. The next day, she disappears. A connection is rapidly made between Lila's case and that of Solène. Meanwhile, Marianne continues to suspect Solène's father.
