It is located in Nairobi, the capital of Kenya, and Leonid went there to find out how people live in a place where living conditions are not even close to being comfortable. About a million people live in Kibera, and there is not enough infrastructure for all of them.

People are establishing health care, cleaning, education and childcare through their own efforts. These are the real heroes of the slums. They'll tell us what drives them and why in this episode of Culture Shock filmed in the African slum of Kibera in Nairobi, Kenya.
