Oliver Shaw is taken hostage and used as a decoy for Kevin Ford's ultimate plan to seek revenge on the officers at 15 Division - specifically those who were involved in questioning his involvement with the abduction of Chris Diaz's son. Many of 15's officers are sequestered to the station as a safety measure but Ford outsmarts them and in the end, shoots another officer. While the officers are dealing with the repercussions of Oliver's abduction, Dov and Wes argue over what course of action would serve Chloe best for her recovery, with Wes having the upper hand as Chloe's husband. In the end, the officers are reunited at the hospital, not knowing whether things will ever be the same.
A fun, fresh, high-stakes drama with a twist of danger follows the lives of five young, ambitious cops right out of the Academy. From their very first day on the job, these rookies are plunged into the world of big city policing, a world where even the smallest mistake can have life-or-death consequences and serious emotional fall-out.
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.
