Archaeologists tell how tomb robbers plundered the pyramids and tombs of Ancient Egypt, and what traces they left behind. In the necropolis for the nobility, they study a flooded luxurious tomb, which was subjected to numerous raids, and was also reused for several centuries. Scientists are investigating one of the most daring robberies of the ancient world - the plundering of a gigantic and heavily guarded mastaba tomb. And in Egypt's oldest pyramid, they'll discover how the builders built their elaborate defenses to protect the treasures within.
