Last season, Andy McNally walked away from her life as “that girl”—that heartbroken girl who puts her career after her personal life— to take on the biggest opportunity of her career. After six months on an intense undercover mission with Nick Collins, she’s ready to come back home. But she quickly realizes that life doesn’t have a pause button; six months is a long time to leave everything behind— especially Sam Swarek.
Andy tries to take the new world order in stride, but things get increasingly complicated when she finds herself butting heads with 15’s newest Senior Officer, and when she unwittingly starts to come between two of her closest friends. Andy must figure out how to balance her own needs against being a loyal peer— all the while trying to be a perfect cop.
