But when they come face-to-face with an out-of-control EDP [Emotionally Disturbed Person], their differences are put to the test and one of them has to pull the trigger. Meanwhile, the rest of 15 Division is on the hunt for an armed burglar following a string of ATM robberies, and Dov is forced to work with rookie Chloe Price who he hooked up with at Frank and Noelle's engagement party. Together they track down the burglar, but Dov is wary of his new partner and her methods. Andy and Dov are both out to prove their history within 15 Division, but soon realize that there's value in having a fresh perspective while on the job.
A fun, fresh, high-stakes drama with a twist of danger follows the lives of five young, ambitious cops right out of the Academy.

The soul of this close-knit group is 26-year-old perfectionist Andy McNally. Honest to a fault, all Andy has ever wanted to be is "good police". Her father was a cop, and while he wasn't the best cop - or the best father - Andy knows she'll never find this sense of family, loyalty and excitement in any other job.
The series explores the trials, triumphs, competition and camaraderie of Andy and her rookie family - boyfriends, best friends, mentors and competitors - who are about to learn that no amount of training can prepare them for life.
