The year is 1874, and Sam Clark and his father, Adam, are riding back to Texas, following a sale of longhorn cattle up in Kansas. All Sam wants is to be home, where his mother, Martha Sue, awaits their arrival. However, nothing is easy in hostile Indian Territory. Father and son are bushwhacked-attacked with no warning. Adam Clark is shot, and in order to save his own life, young Sam must flee. As he flees, he realizes there was something familiar about their attackers. Could it be? Was his father murdered by a neighbor, or even worse, a friend?
