"Waco, push your luck and you’ll be pushing up flowers in the Pinos Altos cemetery"

U.S. Marshal Lance Kincaid left the hill country of Texas in pursuit of his father's killer. He believed the killer was headed for Pinos Altos, New Mexico. During his journey, he encountered run-ins with outlaws, renegade Indians, and Comencheros.

When he arrived at Fort Griffin, Texas, he was told the fort Commander's daughter, Amy, had been kidnapped and was being held for ransom. He and his partner, Hefty, were given the task of rescuing her.

In route to Ben's Fort, he came upon the massacre of a peaceful band of Lipan Apaches he had befriended years before. Lance decided to put the search for his father's killer on hold while he tracked down the perpetrators of this crime. He found at Bent's Fort that his two searches converged. After assisting the military unit stationed at Bent's Fort with several missions, he and Hefty proceeded to Pinos Altos by way of Taos, Santa Fe, Fort Craig and Fort McRae.

He and Hefty faced a number of challenges, some man-made and others of nature, while traversing the Black Range Mountains to Pinos Altos, the territory of Geronimo. With the assistance of Sheriff Roy Bean, and the elimination of Waco, Christian's hired gun, they tracked down the killer. Their final task was to bring the killer back to Texas for trial.
