The picturesque Fjällbacka has been tested by tragedies in the past, but nothing has shaken it as much as the body of a little girl in a fisherman's nets. The results of the autopsy are shocking – it is not an accident. 

Inspector Patrik Hedström, who has just become a father, takes on the sad duty of discovering who is behind the premeditated murder of a child, whom both he and his partner Erika knew very well. He knows that the answer lies in the why. However, he does not know that this case will lead him to delve into the dark core of Fjällbacka and the town's past, a journey that will shatter its idyllic appearance once and for all.
