In the aftermath of Fred's house explosion, Officer Nolan and Bailey discover there's more to Fred's death than meets the eye. Meanwhile, Officer Chen and Officer Bradford demand a treasure hunt rematch and enlist Officer Grey to help set the terms to a new bet, all while they arrest a series of wealthy female criminals. Elsewhere, Wesley struggles to keep it together under the pressure of his debt to Elijah.
Starting over isn't easy, especially for small-town guy John Nolan who, after a life-altering incident, is pursuing his dream of being a Los Angeles police officer. As the force's oldest rookie, he's met with skepticism from some higher-ups who see him as just a walking midlife crisis. If he can't keep up with the young cops and the criminals, he'll be risking lives including his own. But if he can use his life experience, determination and sense of humor to give him an edge, he may just become a success in this new chapter of his life.
