While working on a high-stakes gun raid, Andy and Gail stumble upon a victim of domestic abuse whose brutal experience in the system has taught her not to trust the police. When Andy promises to protect the woman from her abuser, she soon learns that it takes more than just following protocol to be good at her job. Meanwhile, the other rookies get caught up in the annual police retirement boxing match – a fundraising event known as “Fite Nite.”

There’s a nervous tension in the air on Judgment Day for all the rookies at 15 Division who will have to undergo make-or-break assessments by Staff Sergeant Frank. But after the death of an unidentified girl at a house party – an emotionally harrowing experience that pushes all of her buttons – Andy begins to question whether she has what it takes to be a copper and contemplates handing in her badge.
