Set during the California Gold Rush, Devil's Ford tells the story of Dick Mattingly, an optimistic but perpetually unlucky prospector, and his idealistic partner George Kearney. When two young heiresses, Christie and Jessie Carr, arrive in the rough mining camp after their father's death, they discover their supposed fortune rests on a failing irrigation project. Despite poverty, the miners maintain honor and hospitality toward the sisters. Just as hope fades and the enterprise collapses, water suddenly rushes through the completed flume, uncovering rich gold deposits and transforming the camp overnight. Amidst newfound wealth, love quietly blossoms between Christie and Kearney.
