Commissioner Krüger is responsible in the Brandenburg Spreewald. Its falls are often linked to the history of the area. He deals with mummified corpses, corpses in fur traps, snake venom, arson, old legends, the GDR past, family matters - and all of that in the picturesque Spreewald. Krüger investigates taciturnly and suspiciously - and the films allow themselves time and quiet.
