After 11 years, Jennifer Lopez is returning to the small screen in NBC's Shades of Blue. But if you're expecting just another cop show, you're in for a (seriously intense) surprise. In the trailer, we see Harlee Santos, an officer with seemingly good intentions who becomes entrenched in the ways of dirty cop business—until she's caught and has to decide whether to become an FBI informant (and betray her peers) or face the consequences.

The show premieres Thursday January 7, at 10/9 c on NBC.
