The narrative follows Richard Darrell, a young officer newly assigned to a distinguished horse-artillery troop in India as he adjusts to rigorous drill, rivalry, and close friendships among his peers. Episodes shift between training and domestic moments, tests of courage, and mounting tension: jealous comrades, outbreaks of temper, field engagements, and a violent confrontation involving a local Wazir that ends in a dramatic rescue. A linked robbery and the search for missing jewels draw in officers and noncommissioned men, and the tale traces questions of loyalty, discipline, and honor through confession and the final resolution of those crises.
