An army scout, Stephen, asks a young woman to marry him, only to discover that she loves another man. Stephen rejoins the army, while the other two get married and have a child. Two years later, the young family heads west as part of a wagon train, while the scout takes part in a brutal raid on an Indian village that leaves the survivors thirsting for revenge. As the wagon train including the young family heads into dangerous country, Stephen is part of the military escort that is assigned to protect it. Not long afterward, when the wagons stop to make camp, Indians stage a carefully planned attack on the camp.
