This is a Belgian/Dutch coproduction series on Netflix, about an undercover cop couple in an xtc producing mob family, based on true events. I normally don't like Dutch movies or series but this one is very good. There is still only one season, but there will be a next season, and a movie (sort of a prequel apparently), and possibly even another season.
I watched it in original language of course, but it is dubbed to many other languages. Which will possibly loose some of its subtleties for some characters are Dutch and some are Flemmish, and they all speak in dialect. Which is like US people versus Canadians. They speak different English.
It plays in the area where I live, most of the times just over the border in Belgium, but they also visit the PSV stadium at one point.
One of my favourite Dutch actors plays in it (at least he played in some comedies that were really funny), but he gets killed in the first episode. The other actors are fine as well though.
