The "SOKO Hamburg" investigates murder cases and crimes transnationally in Schleswig-Holstein, Hamburg and Lower Saxony. Their cases range from Ratzeburg over St. Pauli, the Port of Hamburg and the Old Country to Kehdingen and Dithmarschen. Therefore, the commissariat of the SOKO is not in a smart new building in the Hafencity, but in an old brick building on the outskirts in Finkenwerder - right on the Elbe, the lifeline of the three northern federal states. And since the river is also often the fastest way to reach the far-flung crime scenes, the commissars are always a speedboat available. As connecting as the river is, the criminals on the river Elbe are so different: Hamburg businessmen and old people apple growers, well-to-do "bacon belt dwellers" and well-known Kiezganoven. To find them, it takes an equally versatile team, a team of people and team spirit, washed with all the waters: These are Jan, Lena, Oskar, Cem and Maria. (Text: ZDF)
