Hannah Henford, travelling West from Ohio with her family aboard a steamer on the Missouri River, meets the reticent Andrew Callahan, a young man also following the trail towards Oregon. The boat docks and during the next part of the journey, the strong and broad-shouldered Andrew captures the heart of Hannah with his bravery, and the two become close. Jeremiah Smith, a mysterious and adventurous mountain man, discovers Hannah alone and takes her deep into the open in search of wild turkeys. Hannah cannot help but be charmed by Jeremiah, but he may not be all that he seems. In Arapaho territory, Andrew will be needed again: he will face peril in pursuit of Hannah; he will face Peril on the Oregon Trail.
