The search for a missing boy leads the team into the middle of a dangerous drug war between two rival gangs.
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.
