Summarize the story's plot. In what way does the plot express themes common to naturalism?

Naturalism, though most often noted for it’s deterministic philosophy and ideas on man and his fate in the universe, had many more characteristics that critics and literary theorists have defined. Among these traits are a focus on the lower classes of society, characters are thwarted of their free will by external forces beyond their control including an indifferent nature, the settings are frequently urban, the world is random, details are not as important as in realism, and life is often cutthroat and cut short.
