When a 6-year-old girl is kidnapped in broad daylight, the shock waves extend beyond her family circle because the little girl - Kimmy - is a star whose videos posted daily are followed by millions of viewers. The investigation is entrusted to Sara Roussel, brigade leader at the SDPJ. To try to save the little girl, Sara will have to dive into a world about which she knows nothing and enter into the intimacy of this family who has learned to live under the gaze of their community. While the little girl's “fans” carry out their own investigation, establish theories and name their culprits, Sara becomes irresistibly closer to Mélanie, the little girl's mother. From confidence to confidence, this mother will reveal her secrets and those of those around her to the point of sowing doubt about the real culprit.
