A restless young engineer leaves home to join a railroad survey in the American West, where he learns frontier skills, befriends an eccentric scout, and faces buffalo hunts, wild mustangs, and encounters with a grizzly. He becomes involved with an Apache chief named Winnetou, which leads to capture, duels, trials, escapes, punishments, and the death of an antagonist called Rattler. The narrative traces tense confrontations, shifting loyalties, and mutual instruction between cultures, concluding with scenes of teaching and a burial that reflect honor, sacrifice, and the costs of survival on the plains.
