In 1885, while his regiment is sent to the Sudan to battle the rebellious Dervish tribes, British Lieutenant Harry Faversham resigns his officer's commission in order to remain with his fiancée Mary Burroughs in England. His friends and fellow officers John Durrance, Peter Burroughs and Tom Willoughby brand him a coward and present him with the white feathers of cowardice. His fiancée, Mary, adds a fourth feather and breaks off their engagement. However, former Lieutenant Faversham decides to regain his honor by fighting in the Sudan incognito.
