The series is set in Hamburg and focuses on the two-man staff of an office of the Kriminalpolizei - the German Crime Squad - specifically a Mordkommission, or Homicide Commission.

This team was also assisted by the main inspector, Theo Micklitz, who comedically yells at the two policemen at the end of each episode about their work.

It is shot on location in Hamburg and its surroundings, though the usage of areas in production is often geographically incorrect.

Guido Bernstein (Xaver Hutter) is the son of the police commissioner and a law-school drop-out.

The dependable Wolfgang Bronski (Matthias Schloo) has been working for the Homicide Squad in Hamburg for two years and gets on well with his boss, the Chief Inspector.
