Chicago P.D.

Chicago PD follows the Intelligence Unit as they investigated crimes in the city of Chicago. It's led by Hank Voight (Jason Beghe) who has a history of stepping over the line however he wants to get results. This series has a gritty feel to it that separates it from other police shows. The best thing about it is the cast (Beghe, Patrick John Flueger, Jesse Lee Soffer, LaRoyce Hawkins, Sophia Bush, Tracy Spiridakos, Marina Squerciati, Elias Korea's, etc.). It's one show of a bigger Chicago Universe that they created along with Chicago Fire & Chicago Med. I personally think Chicago PD is far and away the best of the 3 and definitely worth watching.
