Notruf Hafenkante plays in the Hamburg Police Department 21 (PK 21). Several events are processed in a sequence. It can be about kidnapping a child or about theft. The police officers work closely with the doctors at the Elbkrankenhaus (EKH), as their cases are linked there again and again. Head of the Police Senior Counselor Wolf Haller and his team carry out the police investigative work; Dr. Jasmin Jonas, the niece of the former district manager, Chief Police Officer Martin Berger, and her colleagues provide medical help, regardless of whether they are victims or perpetrators. Overall, Notruf Hafenkante is about an entanglement of two different and yet close working days and the private life of the rescuers.
