The place-central Oregon in 1909-11 when the Oregon Trunk was being put through. The scene-America's ""last"" frontier-battleground for the contending forces of Hill backing the Oregon Trunk and his rival Harriman. Key to it all is heroine Hanna Racine's ranch in the narrow ravine of the upper Deschutes. Onto the scene come tall, handsome, two-fisted hero Lee Dawes, and his side-kick-second male lead Mike Quinn. Plot thickening is provided by Cyrus Jepson, mysterious ""third force"" in the struggle, and a girl in his hire-dark, sultry Deborah Haig who makes both Dawes' and Quinn's blood boil at the mere droop of a suitably long black eyelash. But all ends well--good girl Hanna capitulates-both to Dawes and the Oregon Trunk, while Deborah and Quinn naturally gravitate into each other's arms. Routine lending library fare.
