It ain't over 'til it's over.

His wife is dead and his son hates him, but this old man still has fight in him! 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.
