Hanna is desperately looking for The Leak within the police department. This is done to get Christian, who is hiding from the Mimicas, home. Dubravka Mimica sells The Leak, but Hanna doesn’t know to whom. She and Björn start looking into it, and Hanna manages to pressure Jovan Mimica into helping her. Hanna is crossing the line ever more, as she puts other people at enormous risk. The question is if she is even prepared to let people die on the way. The trail finally leads to a much larger organization than she and Björn had been able to imagine. A circle that is closer to them than they had thought.
