A man's body is found in the harbor. Liv Moormann (Jasna Fritzi Bauer) and Linda Selb (Luise Wolfram) find out: The dead man (Markus Knüfken) was a doctor – and what a doctor! A do-gooder, a Samaritan, one who treated the town's poor pro bono, a helper with great ideals. And now he lies here, executed, on a dusty harbor quay - run over and with his skull crushed in. What is the secret behind the brutal act? Whose anger and hate has been vented here? At first, no motive is recognizable, the traces in the vicinity of the dead run into nothing.
Moormann and Selb investigate meticulously and find a number of suspects: the medical assistant Kirsten Beck (Lisa Jopt), the activists Ann Gelsen and Vicky Aufhoven (Anna Bachmann and Franziska von Harsdorf) andCharlotte Aufhoven (Karoline Eichhorn), the boss of a once posh family business. They all have a lot to hide because they have a lot to lose. The crew of a freighter anchored next to the scene of the crime also remains silent. That's the job for the Dane Mads Andersen (Dar Salim), who tries to hire on the freighter and get more information that way. But this time he cannot convince either the captain or the crew - the situation escalates and Mads Andersen is in serious danger. He also has his own battle against shadows from the past.
This "crime scene" negotiates the relationship between a sense of duty and happiness in life, deals with guilt and atonement and is a plea for the inner freedom of each individual.
