Matthew Devereaux (Spencer Tracy) is a ranch owner who has built an enormous ranch and mining empire. He raised his sons to carry on his fierce, hard-working Irish settlement spirit, that helped make him a success. However, as a consequence, he's never shown his three older sons by his late first wife, Ben, Mike, and Denny (played respectively by Richard Widmark, Hugh O'Brian, and Earl Holliman), his affection as a father. He treats these grown men (in their 30s to their 40s) little better than hired help.
