Kibera is the biggest slum in Sub-Saharan Africa. Even before they go to school here, children must run the gauntlet of chaotic and even violent streets. Scientists warn that too much stress can permanently change the architecture of young brains, but insufficient stimulation can also be a problem. The adults of Kibera are working hard to offer kids safe and stimulating pre-schools, but pre-school brings dilemmas. Should it reflect traditional African social values or the West's more individualistic outlook? And what of the children receiving no stimulation at all? Accessibility options on the DVD are: (1) audio description, (2) English subtitles in a black box.
