Morden im Norden plot
Former police officer Finn Kiesewetter returns to his old profession after his farm is set on fire and he has accumulated significant debt. He is transferred to his old district in Lübeck and becomes Sandra Schwartenbeck's new colleague. In his former hometown, he meets many acquaintances from his childhood, including his former lover Elke Rasmussen, who is now the city's prosecutor. Because he initially did not have his own flat in Lübeck, Finn Kiesewetter lives with his aunts Toni and Ria, who run a tea shop in the city center and put a lot of energy into finding Finn a new wife or girlfriend.
