The cruel death of a young woman presents the investigators Hanna Landauer and Lars Röwer with an extraordinary challenge: They know both the perpetrator Robert Lessing and his next, his actual victim: Anne Herbst, the older sister of the dead woman. Anne lives under a false identity in a therapeutic shared apartment in northern Sweden. Here, near the Arctic Circle, she retreated and hid from her ex-boyfriend Robert, who stalked her heavily after the relationship ended and almost murdered her. Her sister was Anne's only connection to her old life. For the experienced investigators it is obvious that Robert now knows Anne's hiding place. They travel to Sweden to bring Anne to safety and confront Robert. But Anne refuses to flee again. And so Landauer and Röwer are only left with one option: they have to set a trap for Robert in the snowy, dark expanses of Sweden and include the deeply traumatized Anne in the plan. Because no one knows Robert better than she does.
