The Pettys are one of the greatest racing families in the history of motorsports - four generations whose pursuit of greatness helped NASCAR become an international phenomenon. Petty Blue is the story of their dramatic rise to the top of a sport, told in their own words. Through vintage film, dynamic race footage, archival photos, and candid conversations, relive Lee (#42) becoming the face of NASCAR in it's earliest years, his son Richard 'The King' (#43) winning a staggering 200 races, Richard's son Kyle (#44) defying expectations and rocking the raceway, and Richard's grandson Adam (#45) breaking records as the first successful fourth-generation competitor in any sport. Narrated by Academy Award Winner Kevin Costner, Petty Blue is more than a movie. It's a family's legacy.
