The story of Chuck Wepner is unique in the annals of boxing. Though he was the inspiration for Rocky, he is most famous for the fights he lost to George Foreman, Sonny Liston, and Muhammad Ali, with whom he went 15 gruelling rounds. A New Jersey guy with a blue-collar work ethic, Wepner was dubbed "The Bayonne Bleeder" due to his ability to take punishment without going down.
Chuck follows Wepner through his peak years both in and out of the ring. The film offers a complex portrait of his domestic life, particularly his marriages. But its main event is his 1975 fight against Ali, with whom the affable Wepner shares an endearing backstage camaraderie.
