“Children Underground” observes the lives of several Romanian street children in Bucharest's Piata Victoriei metro station. These children live in the station's tunnels and corridors, in almost indescribable conditions; they sleep in cardboard, and they beg and steal and prostitute themselves for food and money. Almost without exception they use drugs, especially the inhalant Aurolac, a cheap, toxic paint that coats their faces in silver. The children bounce in and out of shelters: they fight; they huff paint; they are beaten. These tattered lives go by in full view of both Bucharest's commuters and the filmmaker’s camera.
