The Beginning - S4.E9

Billy Horne is a white man who was captured by the Shoshone when he was six. He comes into Ben & Joe's campsite one night uninvited. They capture him and take him to town. Roy Coffee wants to put him in jail for safekeeping, but Ben says he'll take him to the Ponderosa. They buy Horne clothes and become friends to him. A guy named Milton Tanner says the deed to the Ponderosa is weak and tries to take a third of it. Billy goes to Tanner's ranch and warns him that he will kill him if he tries to take the land. Tanner turns his dog loose on Billy. Billy kills the dog and then Tanner, who is going for a gun. Billy pleads guilty, but breaks out. Eventually he goes back with Joe and tells what really happened.
