Two girls pursue art careers in New York, sharing a dingy, one-room flat. One grows sick when her paintings fail to sell. Only a vigorous desire to live can enable her to survive.

The morning after a fierce wind storm, when surely all the leaves will be gone, she sees a single leaf remaining. (Enjoy more O. Henry in "The New York Stories.")
