Synopsis

Sophie Cross, a brilliant attorney, is enjoying a lovely summer day in the North Sea dunes with her 5-year-old son, Arthur, when he vanishes into thin air. She only leaves the boy alone for a few seconds, but that’s all it takes. It’s the start of a horrible nightmare for Sophie and her husband Thomas Leclercq, a razor-sharp police commissioner who’s crushed by his son’s disappearance and finds himself powerless to solve it.
