Ruthless Vince Carden dominates the Arizona-territory town of Forge River and buys the scalps of murdered Indians. He has driven his brother Paul from his home, and this leads to the total disillusionment of his wife Martha. Haunted by the mysterious death of a girl he had loved, Paul ends his wandering and joins a wagon train heading for Forge River; with the train is Kate Mayfield, who is returning home after years of school in the East. Paul and Kate are the sole survivors when Apaches attack the train, in reprisal for a slaughter staged by Vince's men. Vince uses the Indian attack on the train as an excuse to lead the raid on a defenseless Apache village, which sparks a massive assault on Forge River. —Les Adams
