Following the presumably Islamist attack on the right-wing populist candidate, Germany is upside down. However, the cell is planning something much bigger to finalize the swing on the right.

Now it is clear what the cell is willing to sacrifice to change the political and social state in Gernany and Europe radically: the life of more than 1000 children.

Asgeir, police officer with the special unit, wants to start a new life with his daughter Michelle in placid Vestvik in Norway. Instead he is confronted with a radical right-wing terror cell.

Poland is in revolt and the European democracy is in jeopardy; Ellen attempts to stop the attack; Asgeir asks Chief to help him; the NATO summit is about to begin as the Minister of Justice makes a crucial decision.

When Ellen and Asgeir learn that they have fallen into a trap, they must make an unlikely ally to escape; the Minister of Justice and the PST face the repercussions of Budapest's events; Tarje gets new information that completely changes his life.

Ragna travels to Germany with Ole and Brehme, where the parliamentary election is imminent. The radical right-wing terror cell is planning to change Europe forever.

Brehme knows that the cell was infiltrated and does everything to find the traitor. Ragna is suspected, as well. Meanwhile, ordered by Inger, Asgeir is coming to Berlin as a back-up for Ragna.

Ellen goes undercover again to track down the infamous Mateusz Krajewski; Ziminov and Asgeir run into difficulties at the border; in Norway, Tarje is in a tough spot where he has to choose between being loyal to his sister and his best mate.
