Travelling from Lusaka to the Gwembe Valley and then on to Kabwe, Kema Sikazwe hears from people living in communities where artefacts were taken. In the shadow of the Kariba Dam, Kema meets people who were forced from their land when the valley was flooded who explain how promises made at the time have not been kept. Finally, at the lead-mining site where the Broken Hill Skull was discovered in Kabwe 1921, Kema meets former workers who describe how their homes remain contaminated, more than 25 years on, the UN estimates they are among 300,000 people living on toxic ground.
