In 1958, an Italian archaeologist discovered the mummified remains of a two-and-a-half-year-old boy in a cave in southwestern Libya. But this was a mummy with a difference: it was far older than any comparable examples found in Egypt. The discovery raised some profound questions. Who were the ancient inhabitants of the Sahara Desert who put the mummy there? And what influence might those people have had on the glittering civilization that later emerged in the land of the pharaohs? This fascinating film follows Italian professor Savino di Lernia and his colleagues on a trek through the Sahara in the search for answers — a journey that leads to some astounding conclusions.
