White Horse Rebels, under the command of a mystery villain known only as The Leader, attempt to create an independent "White Horse Republic" in Canada's north west. Funded by gold from the Marrow Mine, they attack Canadian settlements in the area. The North-West Mounted Police, represented primarily by hero Sgt. Ward and his sidekick Constable Nevin are, work to top the rebels and discover The Leader's real identity. An added complication comes in the form of First Nations, Blackfeet driven into Canada from the United States, who attack both sides and whom the rebels attempt to use as scapegoats for their own attacks.
