Dawn French introduces an update to a moving documentary first broadcast on BBC4 last November. Where the tarmac ends in rural Zululand, South Africa, a human tragedy of epic proportions is being played out against a backdrop of vast landscapes and rustic poverty. Hundreds of thousands of children are being orphaned by the Aids pandemic that is tearing at the heart of one of the wealthiest countries in Africa. This film chronicles the story of some of the children who have been left alone stigmatised and grieving.
