The story is told from the point of view of some young students, who find themselves acting as nurses to wounded soldiers to help their city. Many of these girls therefore have no manual skills in rescuing an injured person or helping a sick person. Between the two main girls there seems to be a bond beyond friendship but the romance component is weak. The narrative of the story is tragic, realistic and with an ending that leaves a bitter taste in the mouth.
