When British teenager Katie Gleason vanishes during a school exchange in southern France, her mother Sarah rushes to Saint-Michel seeking answers.
Met with evasive police and hostility from Katie's powerful host family, the Morvans, Sarah launches her own investigation alongside local detective Lieutenant Virginie Taylor, exposing buried secrets, abuse, corruption, and trafficking within the tight-knit town.
As bodies surface and suspicions reach influential figures - including Virginie's father - alliances fracture. Betrayed and unraveling, Sarah learns that Katie may still be alive. Time is running out for them both and justice.
