When one of Fjällbacka's lobster fishermen finds a little girl drowned, her death is said to be an accident. But the autopsy reveals traces of fresh water combined with soap in her mouth. The conclusion is that someone has drowned the girl indoors, undressed her and then thrown her into the sea. But who could have wanted to do such a horrible thing to a little girl? And why? Patrik Hedström, whose girlfriend Erica has just given birth to their first child, once again becomes involved in a complicated murder investigation together with his colleagues at Tanumshede's police station. Behind Fjällbacka's idyllic façade lurks another reality - with feuding neighbours, family conflicts and child pornography rings.
