One of the best and most underrated police dramas on television. Follows an anti-corruption squad in an unnamed city in northern England (Birmingham?), that pursues bent coppers and crooked politicians.
The list of police procedurals out there can seem endless, but if you're feeling overwhelmed just think of all the police officers who not only have to solve these crimes, but fill out the paperwork as well.
London may be England's capital, but the underbelly has outposts across the country, from second-cities to the countryside. Thankfully, there's no shortage of quality law enforcement outside the Big Smoke.
