S3, E1: Andy McNally is trying to make the most of her suspension from 15 Division. In fact, sheʼs on vacation -- 15,000 feet above the earth, parachute strapped to her back, about to jump out of a plane -- when she gets a call telling her to come back for her Tribunal. At 15 Division, Andyʼs real life comes flooding back when she reunites with her friends, and meets her possible new replacement – new rookie, Nick Collins, whoʼs not only ex-military, but also Gailʼs ex-fiancé. Tensions rise when Andy comes face to face with Sam Swarek— whom she left three months ago without a word. But before Andy can explain her reasons for leaving Sam, theyʼre involved in a serious highway collision. In the messy aftermath of a brutal 4-car pileup -- and right before a van full of chemicals catches on fire -- Andy saves a young girl hiding in the back of the van. Things get even messier when the girl disappears from the chaos of the scene. Andy, the only eyewitness, connects the girl to a 7-year-old cold case, and works with the cops to find the missing girl before itʼs too late.
