The head of the Danish migration agency is murdered brutally, and the murder is linked to a controversial expulsion case. Investigator Henrik Sabroe needs help from his colleague and friend Saga Norén, but she is in prison for the murder of her mother.

Henrik and Saga suspect that Taariq and the missing expert on left-wing radicals are hiding something, and collaborate to reveal them. They disagree on how to handle the homeless girls who still refuse to give up their identity.

Taariq recognizes a car related to the case. He wants to push the owner for money, but is himself accused of robbery. Saga fears that will be more murders and Henrik's efforts for the homeless girls end up in disappointment.

Saga and Henrik keep searching for a link between the murder victims. Lillian is reprimanded by her superiors. Dan finds out where his ex-wife and son are and causes trouble. The relationship between Saga and Henrik is tested to the limit and may have hit its breaking point.
