Marlo reveals to Andy that she's been watching suspected pedophile Kevin Ford for days. When Andy answers a home invasion call and finds Ford badly beaten, she fears the investigation will point back to Marlo. She contacts Swarek, who is stunned by the news and scrambles to cover Marlo's tracks - recruiting Andy to help. Together, they keep the spotlight off Marlo long enough to find the assailant. But Swarek and Andy are left shaken by the day's events and the choices they've made. Meanwhile, Traci oversees a major drug sweep, with Chloe, Nick, Dov and Gail assisting. While 15 Division is poised to break the single week record for drug collars, Sam leaves his post with Traci to help Marlo, causing the operation to take an unexpected turn. Traci reaches out to Steve Peck for help, and together they attempt to capture a ruthless gang leader.
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.
