A young policewoman is shot dead, her partner Daniel Weiss (Barnaby Metschurat) and his daughter Lisa (Luna Esteban Loos) have disappeared. Is it an act of a relationship or is there much more behind the murder? Helen Dorn (Anna Loos) and Gregor Georgi (Matthias Matschke) set out to find Weiss, an accomplished marksman who has been seen with his sniper rifle in Düsseldorf. But then a completely different, much bigger opponent reveals himself: Weiss is in the grip of a blackmailer (Joachim Król) who is threatening an attack on the Düsseldorf drug scene. Under enormous time pressure, the investigators must stop a perpetrator who has nothing to lose, find a child who is being used as leverage and track down a father who would do anything to save his daughter.
In addition to Anna Loos, Matthias Matschke and Stephan Bissmeier in the continuous roles, Joachim Król, Barnaby Metschurat, Oliver Bröcker and Marek Harloff, among others, are in front of the camera in the episode roles. Markus Imboden is directing from a script by Nils-Morten Osburg.
