For the scarlet lips of a traitor's woman - he stood alone - against the mighty Chief Red Cloud and the scalp-hungry hordes at his command!

The Great Sioux Uprising

During the Civil War, in Wyoming, horse dealers Joan Britton and Stephen Cook are competing to supply the Union Army with horses. A Cherokee is in the area to stir up the Sioux against the Union just as Cook decides to steal a herd of Sioux horses. Ex-army doctor Jonathan Westgate opposes Cook’s unscrupulous methods as well as being Cook’s rival for the affections of Joan. It seems Westgate is the only one able to prevent a new Indian war.
