Where We Left Off: After a long cat and mouse game, Lt. Wozniak (Ray Liotta) learns that Harlee (Jennifer Lopez) is the rat in his department of shady cops. And Harlee has a whole new set of problems when she kills her ex, Miguel (Antonio Jamarillo), in a move that's part rage and part self-defense.
What's Next: Harlee sets the tone for the season in the first few scenes, having to dispose of Miguel's body. Now she's got to keep that secret, but it's almost the least of her worries. It turns out FBI agent Robert Stahl (Warren Kole) had been using her and Woz in order to get at a much bigger prize -- someone who's infiltrated their department's ranks at a much higher level than they could've anticipated. And why is Woz suddenly single a few episodes in? He had some secrets too, you'll remember, one of which is coming to light.
