Die Ermittler - Nur für den Dienstgebrauch

November 4, 2011: After their latest bank robbery, Uwe Böhnhardt and Uwe Mundlos set their camper on fire and allegedly shoot themselves. Inside the camper, the police find their bodies and secure an arsenal of weapons. Then, Beate Zschäpe's apartment is blown up in an explosion. Police investigator Paul Winter is convinced that Zschäpe is hiding close by... In the late 1990s, Winter arrests Zschäpe for the first time. However, Zschäpe as well as her comrades Böhnhardt and Mundlos are let go time and time again. When the police find explosives in their garage, the trio outwit the authorities and go underground. Both Winter and his colleague Ahler become suspicious when Siebert, their superior at the State Office of Criminal Investigation, insists that Zschäpe, Mundlos and Böhnhardt have fled the country. Winter and Ahler pursue their investigations on their own.
