After thousands of years, Egyptian mummies are speaking from the grave. With the use of state-of-the-art computer tomography scanning, known as CT-scanning, we explore inside a 2,000-year-old mummified body of an Egyptian child. With today’s technology, mummies are studied without being unwrapped. Researchers travel around inside the mummy’s head and body with 3-D imagery. We meet Dr. Robert Brier, a renowned Egyptologist. Dr. Brier reveals secrets of Mummification–it took up to 70 days to preserve the dead. Aided by new technology, we investigate the death of one of the most famous mummies, King Tut. Was he murdered or did he die from an illness? We also uncover the case of the Mummy who lay in obscurity for over a hundred years, until modern science unlocked the secrets of his identity as an Egyptian pharaoh. And we join a team of conservationists as they build a nitrogen-filled glass display case to provide a safe sanctuary to prevent mummies from decay.
