A Mexican scout and tracker named Pedro Felipe navigates a sun-blasted frontier to recover a hidden hoard after rescuing his master's daughter from a band of outlaws. Having slain a lieutenant and taken his ornate weapons, he returns alone to a haunted flatland called the Land of Silence to search a hollow hill and its cave for treasure. The narrative alternates vivid natural description and tense action, following his cunning, superstition, and greed as he faces desert heat, wild animals, and the lingering menace of the outlaw band while probing subterranean passages and old betrayals.
