Dick Wolf is the man behind this series as well as the monster series (and all its spin offs) Law & Order. That is a good start I would say. Plus this one is a kind of companion series for Chicago Fire. That is about fireman working in Chicago’s station 51 while this one is about a special intelligence unit of the Chicago Police Department. The boss of the unit is Sergeant Hank Voight (played by Jason Beghe), a crooked cop who is tough as nails. He has made a deal with Internal Affairs allowing him out of jail to run this unit in exchange for him using his past connections to bring down some big time criminals. Under him are Antonio Dawson (played by Jon Seda), Erin Lindsay (played by Sophia Bush), Alvin Olinsky (played by Elias Koteas), Jay Halstead (played by Jesse Lee Sofer), Adam Ruzek (played by Patrick John Flueger) and tech expert Sheldon Jin (played by Archie Kao). Action-packed show with plenty of drama and a little romance thrown in for good measure.
