A murder without a motive? - Inconceivably. And yet the murder of the 48-year-old senior physician Hermann Johns seems completely unfounded. The renowned physician, who worked in the maternity ward of a Cologne clinic, seems to have been popular with patients and hospital staff alike.

Franz Leitmayr and Ivo Batic are in an internal competition for "Policeman of the Year". Then the phone call: a dead man in the new Jewish synagogue, presumably outside their jurisdiction. The public prosecutor begs them to be sensitive in their inquiries in the Jewish community, but the investigators approach the case like any other.

Cologne DIs Ballauf and Schenk proceed to investigate the neighbourhood where the man had lived. The neighbours have all kinds of relationships: quarrel over a boundary, fathership of another's daughter... but where is a motive for murder?

Feline Wagner disappeared a year ago and a friend reported her missing. Now her body is found by chance in a burial forest during preparations for an urn burial. An argument at the site distracts Faber: It's hard to miss the fact that Commissioner Bönisch and the KTU member Sebastian Haller are already having their private dispute on duty again. Observing that Martina Bönisch's emotional life is putting a strain on herself and her work doesn't leave Faber unmoved.

Rosa Herzog and Jan Pawlak contact the Ihle funeral home: The gravesite was reserved here, a few days after Feline Wagner disappeared. It was paid for in cash by a man who gave a false name. Another murder victim is rescued, just a few steps away from the first. There was a year between the two murders - and soon twelve months have passed again...

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.
