'Chicago PD' Season 7 Episode 12 Preview: Voight and Upton clash as Intelligence tries to take down dirty cops

Sergeant Hank Voight on 'Chicago PD' is by no means what one could call a squeaky-clean cop. However, as fans of the show agree, he is the lesser of many evils in that he strives to punish the bad, even though his methods may be questionable. 

In this week's episode, the case involves a cast of drugs stolen from police evidence that was supposed to be destroyed. This means, of course, that the perpetrators are a rogue group of dirty cops.

To catch them, Voight needs to collaborate with everyone starting from Superintendent Jason Crawford to his CI, Darius Walker, a local mob boss. To take the dirty cops down, Voight makes a deal with Darius.

However, things do not go as planned and it would seem that one of the dirty cops could very well be someone the Intelligence Unit knows and trusts.

This would be why Detective Hailey Upton clashes with Voight and try to enact her own justice. What Voight wants and what the right thing to do rarely syncs up, and though Upton has understood Voight's methods so far, she may not for long.

The good news for fans is that Detective Jay Halstead will be back in action this week. Last week, we saw that he was still assigned to desk duty while he was recovering from the gunshot wound he sustained in the fall finale.

Halstead would understandably be offering support to Upton as his partner did to him in the past. What remains to be seen is whether Upton's undisclosed feelings for him might come out or not.

Meanwhile, fans would also be expected to see what could come next with Adam Ruzek and Kim Burgess, on whom the episode centered on last week. The two of them agreed to deal with the pregnancy together and an intimate moment at the end of the last episode means that "Burzek" could still end up together again.

'Chicago PD' airs on NBC on Wednesday nights.
