On Amrum, a small northern island, the director of an orphanage is found dead. Local police are suspecting a natural cause of death, but an autopsy shows he was murdered. Chief Inspector Lena Lorenzen is surprised that her boss Warnke is assigning this case to her, because he previously removed her from the special commission of investigations and petitioned for her demotion. Lena, born and raised on Amrum and left the island fourteen years ago, forced to plunge into unpleasant memories associated with this place. The investigation entrusted to her turns out to be difficult. Not only people from the immediate circle of the deceased, but also famous people come under suspicion. Only gradually does Lena understand why her boss sent her to Amrum.
