A battered Cavalry squad ... a white girl ... and a renegade Indian princess ... they made the stand that saved the Frontier !

Led by an incompetent Lieutenant, a troop of soldiers is on the Tomahawk Trail in Apache territory. When he lets the Indians steal their horses and gets slightly wounded in a skirmish, Sergeant McCoy takes over command. McCoy successfully gets them to the fort only to find all the soldiers have been murdered by the Apaches. He prepares the troops for an attack knowing if they survive the Lieutenant plans to have him court marshaled.
