Sierra (1950)

Ring Hassard and father Jeff, wild horse breakers, live in a hidden mountain eyrie because Jeff is wanted for a murder he didn't commit. But 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 turns out to be a lawyer) labors to clear the Hassards; but others would prefer them dead.
