Sean Thornton (John Wayne) in an American boxer who swears off fighting after he accidentally kills an opponent in the ring. Returning to the Irish town of his youth, he purchases the home of his birth and finds happiness when he falls in love with the fiery Mary Kate (Maureen O’Hara). But her insistence that Sean conduct his courtship in a proper Irish manner with matchmaker Barry Fitzgerald along for the ride as “chaperone” is but one obstacle to their future happiness: the other is her brother (Victor McLaglen), who spitefully refuses to give his consent to their marriage, or to honor the tradition of paying a dowry to the husband. Sean could care less about dowries, he would’ve punched out the bullying McLaglen long ago if he hadn’t sworn off fighting. But when Mary Kate accuses him of being a coward and walks out on him, Sean is finally ready to take matters into his own hands, the resulting fistfight erupts into the longest brawl ever filmed, followed by one of the most memorable reconciliations in movie history!
