For Micky Ward (Mark Wahlberg), boxing is a family affair. His tough-as-nails mother is his manager. His half-brother, Dicky (Christian Bale), once a promising boxer himself, is his very unreliable trainer. Despite Micky's hard work, he is losing and, when the latest fight nearly kills him, he follows his girlfriend's advice and splits from the family. Then Micky becomes a contender for the world title and he -- and his family -- earns a shot at redemption.
