The Rookie 1x20 Promo "Free Fall" (HD) Season Finale Nathan Fillion series

Starting over isn't easy, especially for small-town guy John Nolan, who, after a life-altering incident, is pursuing his dream of becoming an LAPD 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 humour to give him an edge, he may just become successful in this new chapter of his life.
