VICE takes a trip to Bogota, Colombia's most inhabited sewers. This documentary basically is covering the life of the lower class, poor children in Bogota, Colombia.
Often those children are badly abused and neglected, and then they move into the sewers to live.
No light, fresh feces, rats, fear of being swept away by the currents when it rains, and fear of the death squads coming after you in the middle of the night to shoot, rape, and burn you alive.
The death squads are made up of police, paramilitary, and rich businessmen or their lackeys, and their purpose is to create a "social cleansing." They literally open up manholes and start firing, or worse, they pour in gasoline and set it ablaze.
