Lt. Tom Brennan is cashiered from the 7th Cavalry on two charges, both unjust: that of deserting his men in the face of a cruel Indian attack, and of entertaining a married woman in his quarters after hours. Tom wanders into the desert and is picked up half-dead by Yuba Bill, a prospector with whom he goes into partnership. The Indians go on the warpath, and Tom rides to the fort and warns the colonel. Tom's innocence is established by the confession of an enlisted man, and Tom is reinstated to the service with full honors, renewing his engagement with Margaret Cranston.

A propaganda re-enactment, co-financed by the Woodrow Wilson government, of the 1890 massacre of 300 Lakota residents of South Dakota, which was portrayed as American military heroism and justified as part of the assimilation effort.

Western starring William F. Cody. A re-cut version of the 1914 film The Indian Wars. Both versions are lost.

U.S. Government surveyor John Field suspects Nanette, the adopted daughter of Cavalry-Major Webb, of being a spy and disclosing government secrets to the Sioux tribe, in their war against the whites. The Sioux attack and Field sees Nanette talking to an Indian, Eagle Wing during the attack. Field and Eagle Wing fight and the latter is killed. Field brings his body to the fort and Major Webb sees that it is long-lost black-sheep son who has turned renegade. Nanette then tells Field that she has been giving Eagle Wing money to keep him quiet and not disgracing her benefactor. Major Webb then reveals, in flashback, that Nanette is not a Sioux but a white girl kidnapped by the Sioux as an infant. Field then asks Nanette to marry him.
