Techno, ecstasy and party, party, party: In the 1990s, Christian, Meike and René were part of the scene and celebrated above the rooftops of Cologne in the legendary "Colonius". It has been around 30 years since the three last saw each other. Now they are brought together by inspectors Ballauf and Schenk after their former friend, the former scene photographer Alex Schmitz, was found murdered in his apartment. He was also a regular at the "Colonius" - has his past caught up with him? A trail on the Internet leads the investigators deep into the old party world and to their former companions. Christian's daughter Svenja also becomes the focus of the investigation. Her mother Gina disappeared without a trace after a night of partying...

When the janitor of one of Cologne's largest brothels falls to his death from the seventh floor, detectives Ballauf and Schenk are called to the scene. Evidence quickly mounts that the victim was pushed and other people's lives might be in danger.

Almost all of Alt-Bützenich is deserted and boarded up. At night a security service checks on everything. It was decided that the houses and the church would have to give way to open-cast mining. Then the climate change brings new hope: the old village can stay. But the once close-knit village community has long since disappeared with the move to Neu-Bützenich. As Dr. When Christian Franzen, the local doctor, is informed that his empty house has been broken into, he immediately sets off - but never returns home. His wife Betje turns to the police, who find her husband - shot dead in the old village. Even though everyone here was a patient of the doctor, he was still not particularly popular. During their investigation, detectives Max Ballauf and Freddy Schenk uncover a torn community. Time cannot simply be turned back here in the lignite mining area.

The 60-year-old alcoholic Onno Steinhaus is found dead in a working-class district of Kiel. Steinhaus had a criminal record for pedophilia and, as Borowski and Brandt quickly find out, lived in complete isolation. Ironically, however, a group of children seemed to have gone in and out of the dead man. Apparently they exploited the dead man's desires, but - as they claim at least - never complied with his wishes. The police officer responsible for the district, Thorsten Rausch, seems to have capitulated in view of the social neglect in his area. Sarah Brandt's investigations bring to light a video that shows a boy - Timo Scholz - in a catchy situation with Onno Steinhaus. Timo denies having been abused. Borowski has to observe that Sarah Brandt is conspicuously often trying to get close to her police colleague Rausch.

In the middle of an event at the police college, a young student freaks out and stabs her buddy. He still dies at the scene in the arms of the helpless main commissioner.

A passerby is pushed in front of a moving truck at the Kiel Fjord: an outbreak of violence from nowhere. Commissioner Borowski is listening to a nearby vocational school. A little later, the main commissioner lands in the intensive care unit with a serious head injury. Mila Sahin is of the greatest concern. Why wasn't she with him when her colleague needed her? She suspects a connection between the senseless act and the attack on Borowski. And then there are these strange calls that reach the main commissioner on the bedside: a girl named Finja claims to have been kidnapped by his sister Celina. Celina Lübbert is one of the girls Borowski interrogated at the vocational school.
