2030, Rain is aeviternal since 2021 in all-America. 9 years of crepuscule, corrosion and torrent. Houston Texas, Horizon Abattoir acquiesces to a dystopian life. All adults of the age 21 and up, including Horizons parents, work as erectors in a project, constructing a 5 meters thick layer of glass accross the State's sky.
