The story opens at General Feversham's residence at the annual dinner that he gives to the ones who are left of the Crimea officers. At this dinner, Harry Feversham, the General's only son, a boy of fourteen, is a guest. After the dinner is finished they tell stories of what happened in the Crimea, and Harry listens intently. The story is carried ahead about ten years when Harry is a captain in the army, showing him with his friend, Captain Durrance. They are both in love with the same girl, Ethne Eustace, and Harry and the girl after a time become engaged. Harry gives a dinner to his brother officers, Captain French, Lt. Willoughby and Captain Castleton, to announce his engagement. During the dinner Harry receives a telegram saying the regiment is ordered on regular service. Harry does not show his fellow officers the telegram as he should have done. They see him throw it into the fire. After they have gone, Harry determines to give up his commission, fearing that when put to the test he will be a coward. To preclude such a possibility he sends in his resignation. His fellow officers have, in the meantime, found out that they are ordered on active service, and next day they see that Harry Feversham has resigned his commission. They decide to send him three white feathers. While a ball is going on at Ethne's home a small package comes addressed to Captain Harry Feversham. He opens it in front of the girl and she asks him what he has done and he tells her. When she brands him as a coward, and striking a white feather from her fan, gives it to him. After this Harry Feversham's father will have nothing to do with him, and he consults his mother's old friend, Lieutenant Sutch, and announces to him that he is going to try and retrieve himself. He sails for Egypt in the hope of being able to do something and make the senders take back their feathers. After a long wandering at last he gets his chance and after many trials and tortures by the Arabs and a thrilling rescue he makes his fellow officers take back their feathers. In the meantime Durrance has been with his regiment in the Sudan and has been struck blind by the glare of the sun. Ethne, taking pity on him, has become engaged to him. Harry returns home to find that Ethne is engaged to another man. One day Durrance overhears them talking and decides for the sake of both of them to give up the girl, thus making Ethne and Harry both happy, and go back to the desert he loved so well.
