Matt Calder (Mitchum), a widower, decides it's time to start a new life with his son, Mark (Rettig). After being robbed and pistol-whipped by gambler Harry Weston (Calhoun) and nursed back to health by Weston's fiancee, Kay (Monroe), Matt takes Mark and Kay on a ride down a roaring river, where they are at the mercy of wild animals and a lawless frontier.
