In "Duel at Dawn," Kodiak and Dugan are dispatched to the Andes Mountains to uncover the truth behind a string of mysterious accidents sabotaging the construction of a vital railroad bridge. As they navigate treacherous terrain and hidden dangers, the tension builds between the two men—both skilled and driven, but with conflicting loyalties.
