I believe this is a Banshee series. This is a delightful series about a man who, after serving 15 years in prison, came out and became the sheriff (illegally) of a small town in Banshee. And how he began to administer justice there, I advise you to see for yourself.
This is a great TV series "Shameless". American. It was after him that pathetic parodies began to be created.
Definitely worth watching for everyone!
