Line of Duty is a dark fictionalisation of the world of "bent coppers." This smart police drama goes places other shows are scared to go . . . so it's no surprise the show has been able to pull in big names like Westworld's Thandie Newton, and make it to forth place of the top searched TV show list. It follows the staff of AC-12, the police's anti-corruption unit, and the various members of the force they're investigating. The show has more twists than a bag of fusilli pasta, but that's exactly what'll suck you in immediately. Few shows get people talking the next day the way this does.
