A missing child. When a four-year-old girl disappears in the woods just outside Fjällbacka, the community is horror-struck. Thirty years ago, a young girl went missing from the exact same spot, and was later discovered, murdered. A murder. Back then, two teenage girls were found guilty of the killing. Could it really be a coincidence that one of the girls - now a world-famous actress - has just returned to Fjällbacka? Detective Patrik Hedström starts investigating, with his wife, bestselling crime writer Erica Falck, by his side. A community torn apart. But as Patrik and Erica dig deeper, the truth becomes ever murkier, because it seems that everyone in the tight-knit community is hiding something. And soon, the residents must confront the fact that they could be harbouring a murderer in their midst.
