A fur-trapper named Kelly, who once saved the life of a Sioux chief, is allowed to set his traps in Sioux territory during the late 1870s. Reluctantly he takes on a tenderfoot assistant named Anse and together they give shelter to a runaway Arapaho woman. Tensions develop when Anse falls in love with this woman and when the Sioux chief arrives with his warriors to re-claim her.
