After the failed attempt to kill a defector who fled to Germany, North Korea carries out a revenge attack in Berlin. It is the most serious attack on the city since World War II.
Major Sophie Decker of the elite German Intelligence unit, Department 89, is ordered that everyone connected with the attack should be hunted down and killed mercilessly. But the clues in tracking them down are few and far between, and tensions begin to show in the department. Especially when those closest to them lose their lives.
Under pressure to deliver quick decisive results, Decker ultimately resorts to reckless and illegal measures.
