Walls imprison the men unjustly sentenced to work as miners at a brutal labour camp. Yet an even greater barrier holds them captive; fear of the camp's ancient Indian curse. But Caine knows no such fear.

Caine is accused of taking part in a bandit ambush, and is taken prisoner by the U.S. Calvary. He meets a soldier that is a conscientious objector that helps him clear his name.

Caine is accused of murder and must seek out a witness who is a member of a gang of Indian scalphunters, who doesn't want to help him. He must also deal with an Apache warrior who wants to kill the witness for his crimes against the Apache.

Caine hears the cry of a child begging to be saved, but there is no child to be found. Only a very young buffalo calf and his mother. Caine protects him from a hunter who is determined to kill him for the hide.
