At the end of a deadly bear hunt across the wilderness of Northern Sweden, the successful hunters are shaken by a grisly discovery. Across in Kurravaara, a woman is murdered with frenzied brutality: crude abuse scrawled above her bloodied bed, her young grandson nowhere to be found. Only Rebecka Martinsson sees a connection.

Dropped from the case thanks to a jealous rival, she now stands alone against a killer who brings death to young and old, spawned by a horrifying crime that festers after 100 years on ice.
