This is one of the best "police" TV series I have seen in a long time.
Yes, it is very "local" taking place in a little known Moravian city of Brno in Czech Republic between two World Wars...not in LA or NYC.
It manages masterfully to blend personal lives of (heroes) policeman with duties that are universal to all policeman anywhere who are fully dedicated to their work. The historical context is accidental but adds flavour of the times. The contrast, the ever present conflict between duty and personal live of a policeman is presented in a firm but intimate manner avoiding unnecessary pathos.
Each episode has entirely different plot, however maintains continuity in personal relationships of heroes creating one complete saga.Episodes gradually introduce romantic plots that evolve naturally without "Hollywood" sugar coating.
One has to be familiar with czech culture to fully enjoy the subtle humor that so well balances the occasional morbidity of policeman's work.
All episodes form a body of cinematographic masterpiece worth seeing!
