Drifting into New Mexico Territory, Conrad Morgan, The Loner is turning his back on the past. Then he rides up on a wagon train of pioneers—and straight into an inferno of death and revenge.

Led by a charismatic fool, a group of pioneers are crossing Apache territory, blind to the danger around them. The Loner would ignore the passing pilgrims if it weren't for a beautiful woman. Then, when he turns his back, the Apaches strike. The night is lit with an unholy fire. Mutilated bodies are left behind. And four women are taken prisoner across the Rio Grande To go where no man should go alone, The Loner joins a brutal band of scalp hunters. His plan is to strike before a notorious Mexican slaver gets a hold of the captive women.

But the first shots The Loner fires might be the easy ones. Getting out of Mexico alive—with two bands of enemies behind him and miles of desert straight ahead—will be the fight of The Loner's life
