Years ago a city’s populace was forced underground by chemical warfare. Drugged by the totalitarian government and forced to become slaves, the working masses started re-purifying the earth’s surface with shoddy, antiquated equipment. Decades passed. Enter the present - The workers have no idea that the surface chemicals are leaking down and slowly poisoning them. As the population grows weaker they are disposed of and their work areas are sealed off. No records of their deaths are kept. Mother, the government overseer of one small group of workers, faces a dilemma when it is time to kill her flock. Does she obey the dictatorship or save the lives of those she has sworn to protect?
