This is an automatically translated description

Lawyer Mikael Brenne is woken up one night by a phone call. It was a client, Nina Sunde, and she was scared. Someone has broken into her house. Mikael rushes to the car, but when he arrives, it's too late: Nina's ex-husband is lying on the floor in the living room, shot dead. It looks like an obvious case of self-defence, and Mikael is sure that Nina will be acquitted, but it turns out that she is not telling the truth, and behind this lie there is another story, so brutal that it is impossible to believe.

This case puts both Mikael and the people he cares about in great danger.
