She'd once come here to kill herself but now Mia Kruger has returned to the picturesque island of Hitra to escape from the violence and madness of her life as a police investigator. But when she is approached by 11-year-old Sofia asking for help in finding her missing friend, her old instincts are awakened. Three years ago, Jonathan disappeared without a trace on his way home from Sofia's house. Mia is just beginning to re-examine the cold case when another crime rocks the island: a teenage girl is found brutally murdered, with Jonathan's name written in her blood. Knowing that the two cases are connected but unable to make the link, Mia calls in her former boss Holger Munch to join the investigation.
