Widowed rancher Martha (Brewster) needs $500 to pay off cattle baron Matt Maguire (Meyer), which happens to be the same amount he's put up for the capture of the wild black stallion roaming the hills. When Martha's son Bucky (Hartleben) captures the horse, he wants to keep him and it's up to ranch foreman Randy (Montgomery)--who's sweet on Martha--to settle the matter.
