 An American soldier goes west to escape the Mexican War and becomes a mountain man. He is taken in by an old trapper who teaches him how to survive. After unavoidably violating an Indian burial ground, he loses his new Indian wife and their adopted child to vengeance, and a vendetta between him and the Crows ruins his idyllic life as a fur trapper. Gorgeous scenery and a great role for Will Geer in a thoughtful meditation on the American West.
