One Hour of Love (1927)

Jerry McKay (Jacqueline Logan), a spoiled and willful society girl, on the eve of a flighty engagement, decides to accompany her father to inspect some property he owns, managed by a handsome young engineer, James Warren (Robert Frazer). Jerry demonstrates her prowess as a marksman, though Warren has forbidden the use of firearms; and Tom Webb (Henry Sedley), an unscrupulous rancher, accuses Warren of inciting his men against him. Warren's stern rebuking infuriates Jerry, and she bets her friends that she can get him to propose within a week. She succeeds in winning his approval and then falls in love with him, but they are temporarily parted when he learns of the wager. She returns, however, to seek his forgiveness.
