Jay Halstead and Erin Lindsay are both Detectives for Chicago PD's Intelligence Unit. A few months ago, they decided to take a break from their steamy office romance despite still being in love with each other. One day an interrogation gets away from Erin, and she risks losing her badge, even going to prison. But the FBI knocks on her door and gives her an offer that she can't refuse, one that will save her reputation, her family, and even give Erin a job she's always dreamed of. However, she'd be in New York and have no contact with her CPD family, including Jay. What Erin doesn't realize is that Jay isn't ready to give up on them, and he has the engagement ring to prove it. Will Jay tell Erin how he feels in time, or will it be too late? Based on the season 4 finale of Chicago PD. These characters are NOT mine. They belong to the writers/producers at NBC.
