Officer Nolan mildly injures himself while chasing down a shoplifter and the local DA wants to charge the suspect with assault despite Nolan's wishes. Meanwhile, Lucy goes undercover, Lopez's wedding venue is seized by the FBI, and Nolan meets his new neighbor.
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.
