A Police Procedure in Welsh?

There's a t v show called hinterland, which is filmed in wales. They film a scene in english, and then they reset and film the exact same scene in welsh. The original bed legose dracula movie was shot ino, english and spanish. If you watch hinterland it really gives you an unsurprising portrait of wales as a dark, rainy, sad, desolate place. Why they always said American detective shows here in the northwest e cause you anything could happen up there in that gloomy, drizzly corner.
