Dave Frome was a man with a secret past, which only a few friends knew. Holding himself responsible for the death of his family, he had vowed never to carry a gun again. He wanted to be left alone to raise cattle on his Broken Arrow spread, but mining interests were in the hills, contaminating the water which brought life to Frome's cattle. Hesta Le Roy, daughter of a neighbouring rancher, was horrified when Frome refused to carry a gun against the miners who had, she thought, killed her own brother. It is not until he sees an innocent man brutally lynched that Frome buckles on his gun to battle with the bad men of both factions and eventually win the hand of the girl he loves.
