A dark fictionalization 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. 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 pack of twizzlers, and it'll suck you in immediately.
