Chicago Pd has rolled out some compelling cases of the week over the last month, but "Open Casket," the penultimate episode of season 12, gets down to business. The Iu need to take down Deputy Chief Charlie Reid (Shawn Hatosy), so it makes sense the episode opened with Hank Voight (Jason Beghe) and Ada Nina Chapman (Sara Bues) conferring on what the best attack plan is.

Spoilers ahead!

Voight and Chapman have been keeping tabs on Reid's increasingly risky operations behind the scenes. The Deputy Chief has slowly but surely been seizing control of gangster Jesus Otero (Juan Javier Cardenas) and his drug dealing operation, and ordering the Iu to arrest any competition. The team hadn't really been keeping up their end of the bargain, however.

Reid threatened Voight during the opening scenes of "Open Casket," and told him to increase the overall productivity of the Iu or there would be trouble.
