Drums Across the River (1954)

Crown City, Colorado, may become a ghost town; the only gold left is in Ute Indian land. Gary Brannon, an honest man who hates Indians, joins a mission to try for mining concessions; but crooked Frank Walker, more realistically, plans to start an Indian war. Gary and his wiser father Sam have their hands full keeping the peace, and Walker has lots more schemes up his sleeve. More plot twists than the average Western.
