Young Brodie Dephrane was forced to watch the murder of his mother by a gang of killers. He grows into a strong, reliable man and a deadly shot with a .45 revolver. Yet, he is a restless man obsessed with a need to protect women who cannot protect themselves and for revenge against the killers. He puts his ranch, his romance and his future on hold when he saves a young woman who puts him on the trail of the man responsible for killing his mother. Brodie's dangerous quest drives him from Utah through Arizona Territory and to a final conflict above New Mexico's Gila River on Deadman's Ridge. But the price of his obsession is found elsewhere – in a place called Bock's Canyon.
