Der Pass / Pagans Peak
The series is downloadable.
It is a krimi based on the plot of "The Bridge"
It is set on the border between Germany and Austria. The dialogue is quite difficult with different accents to contend with and on Sky, only english subtitles are available.
On Netflix, I came across "Charité"
Set at the end of the 19th C, it is about the work of the famous bacteriologists Koch, Erlich and Behring as seen through the eyes of a young nurse who wants to be a doctor when that is not possible in Germany. It focuses more on the emotional lives of the characters rather than the science.
The dialogue is relatively slow compared with other shows.
