Western where Indians talk trash about whites

A town—where everyone seems to be named Johnson—stands in the way of the railroad. In order to grab their land, robber baron Hedley Lamarr sends his henchmen to make life in the town unbearable. After the sheriff is killed, the town demands a new sheriff from the Governor, so Hedley convinces him to send the town the first black sheriff in the west.

Black Wolf, a brave, wants Whispering Water to be his squaw. Whispering Water is afraid of this taciturn Indian and refuses. He tries to carry her off but is stopped by another Indian, Brave Heart, and there is a savage light in which Black Wolf is worsted. He appeals to the chief to banish Brave Heart.
