Policeman Asgeir moves to an idyllic town in the west part of Norway. After a local conflict, he meets a mysterious woman named Ragna, and soon they are both trapped in a network of right-wing radical forces that threaten Europe.




Asgeir has just moved with his daughter to a small, picturesque town in Western Norway. But there are dark forces at play, and soon Asgeir is involved in something far greater than just small-town crime.
Asgeir has to deal with the consequences of his actions, and several problems follow when a threat from the past reappears. In the meantime, Ragna must enter into an agreement with Asgeir to protect her identity.
The plan has been implemented. How far is Ragna willing to go to become part of the group and continue her mission? Asgeir's identity has been leaked, and now neither he nor his daughter are safe anymore.
When the terrorist cell crosses the border into Germany, they encounter a security breach. Ragna and Ole must seek refuge in the country, where Ragna discovers how influential her blog can be.
Ragna has been locked up in an abandoned factory hall, and her identity is threatened. There is a leak inside the terrorist cell, and Brehme is prepared to use all means to smoke out the infiltrator.
After she arrives in Berlin, Ragna gets closer to Ole and learns more about the ideology behind the cell's plan. But just when she thinks she's in control of the situation, her worst fears come true.
Ragna must find Cato and stop the attack Ole has told her about. But time is running out, and she sees no other way but to cross a border she never thought she would cross.
The attack is underway, and is taking a personal turn. Ragna hurries to find Ole and stop the attack in time. While Kathi finally takes the matter into her own hands, and goes straight to the source.
Asgeir is in Lofoten, chasing down a money trail to try and catch Ziminov. Ellen is on a leave of absence, at home taking care of her elderly father. But she is restless and impatient to get back to work in the PST.
With the new lead, Ellen and Asgeir rush off to Budapest to arrest Ziminov with the help of CIA.
Ellen and Asgeir realise they have been lured into a trap, and must make an unlikely ally if they are to escape.
Ellen goes undercover again to get to the infamous Mateusz Krajewski, while Asgeir and Ziminov get in trouble at the border. In Norway, Tarje faces a difficult situation where his loyalties are torn between his sister and his best friend.
Ellen has taken Krajewski and his wife as hostages, and they are heading to the TV-station in Warsaw. While Asgeir and Tereza must break into a heavily guarded warehouse in search of evidence.
Poland is in turmoil and the European democracy is in danger. Ellen goes to find Sikora and stop the terror attack, while Asgeir seeks help from Chief, unaware that Michelle's life is in danger.
