Left behind in China by her father, who has gone to North America to find work, Choon-yi has made her living by selling her paintings in the market. When her father writes one day and asks her to join him, she joyously sets off, only to discover that he has been killed. Choon-yi sees the railway and the giant train engines that her father died for, and she is filled with an urge to paint them. But her work disappoints her until a ghostly presence beckons her to board the train where she meets the ghosts of the men who died building the railway. She is able to give them peace by returning their bones to China where they were born.
