The Four Feathers (2002)

"Freedom. Country. Honor. Passion. To save his best friend, one man must risk everything he loves."

A young British officer resigns his post when he learns of his regiment's plan to ship out to the Sudan for the conflict with the Mahdi. His friends and fiancée send him four white feathers as symbols of what they view as his cowardice. To redeem his honor, he disguises himself as an Arab and secretly saves their lives.
