A documentary about the sport of boxing, as seen through the eyes of champions Mike Tyson, Evander Holyfield and Bernard Hopkins.

When he loses a highly publicized virtual boxing match to ex-champ Rocky Balboa, reigning heavyweight titleholder, Mason Dixon retaliates by challenging Rocky to a nationally televised, 10-round exhibition bout. To the surprise of his son and friends, Rocky agrees to come out of retirement and face an opponent who’s faster, stronger and thirty years his junior.
