During the Civil War, Colonel Kern Shafter (played by Ray Milland) and Captain Edward Garnett (played by Hugh Marlowe) become embroiled in a conflict, the cause of which is somewhat cloudy. As a result, Shafter leaves the Eastern Cavlary and moves West, where he is able to re-enlist. Ten years later, Shafter is reassigned to an outpost in the Dakota Territory -- one that is commanded by his old nemesis Garnett. Garnett takes advantage of his authority to assign Shafter to the most dangerous missions, clearly hoping that he will not return from one of them. Things are not made any easier by the fact that both men fall in love with the same woman (played by Helena Carter). The situation comes to a climax during the Battle of Little Big Horn, when both men attempt to put an end to their personal war as hundreds of others are slaughtered around them. Victorious, Shafter manages to survive the massacre and return to claim the woman he loves.
