Weekend in Berlin: party-goers and party-goers roam the wintry streets in search of an unforgettable night. A young woman uses a dating app to find a suitable date in the couple Dennis Ziegler (Vito Sack) and Julia Hoff (Milena Kaltenbach). The next morning, a body is found near Dennis' apartment. Her face is disfigured, making identification impossible.
A missing persons report and a subsequent DNA comparison reveal to the inspectors Nina Rubin (Meret Becker) and Robert Karow (Mark Waschke) that the dead person is the medical student Sophia Bader. When Rubin and Karow bring the news of death to Marianne (Andreja Schneider) and Helmut Bader (Rainer Reiners), the parents deny that the dead woman is their daughter and deny that she used dating portals. To the surprise of the inspectors, Dennis Ziegler and Julia Hoff appear at the police station. They explain that they broke up the same evening after consensual sex with Sophia. But Dennis doesn't seem innocent. A thick police file bears witness to allegations of arson, assault and rape. But he was never convicted.
The suspicion quickly arises that his parents - the patrol officer Doris (Jule Böwe) and the security expert Claus Ziegler (Andreas Döhler) - have repeatedly managed to pull their son's neck out of the noose. And again the parents' fingers seem to be involved, the investigators run into a wall. Rubin and Karow have to use drastic methods to break through the psychogram of the Ziegler family - and to understand why Sophia's parents so vehemently deny their daughter's death.
