Sierra: Ring Hassard and his father Jeff, wild horse breakers, live in a hidden mountain eyrie as Jeff is wanted for a murder he didn't commit. Things change when they take in a lost young lady, Riley Martin, who finds that Ring has "never seen a woman close up." Jeff is injured, Ring runs afoul of horse thieves and the law, and Riley (who is a lawyer) labors to clear the Hassards (who others would prefer dead).
