Gladys Aylward (Ingrid Bergman), a British maid, believes that she is destined to go to China. She is rejected as a missionary, but she eventually finds her way to the town of Yang Cheng and happily runs an inn there. Her peaceful existence, however, is interrupted by Japan’s invasion of China. Aided by Lin Nan (Curt Jurgens), a half-Chinese/half-Dutch military officer, Gladys must lead a group of orphans to safety by embarking on a dangerous mountain journey.
