This story of the Black Hills consistently tells of the unrequited love of a Sioux brave for his chief's daughter, and how he premonished the awful results of her ominous marriage with a white cowboy. Clear Eyes, the daughter of Chief Thunder Cloud, is beloved by Comata, a Sioux brave, but having met and listened to the persuasion of Bud Watkins, a cowboy, leaves her mountain home to become his squaw. Poor little confiding Clear Eyes lives only for Bud, and he at first seems devoted to her, but at the end of two years, a little papoose arriving meanwhile to bless their union, he tires of her, and courts Miss Nellie Howe, a white girl, who thinks him single. Comata, however, has unremittingly watched his movements, and vows to avenge his lost one. Following him to the white girl's home, he sees enough to convince him of the whelp's villainy, so he goes and reveals the truth to Clear Eyes.
