After a deadly virus plagues Mexico City, it's citizens go underground to the METRO. Unfortunately only a small fraction make it inside before the METRO is sealed off. 20 years later a society has formed underground in the METRO. A group of enforcers called La Hermandad or The Brotherhood, who bully and extort people out of their resources, are preventing people from leaving the METRO to maintain control. Dispite this, a group of young rebels decide to escape the METRO by breaking the main sealed off entrance.
