To the ancient Egyptians, life after death was a high-stakes underworld journey fraught with terrifying obstacles: fiery lakes of death, battles with bona fide monsters and ultimately eternal death or resurrection with the sun. It's a journey each Egyptian believed was real and for the pharaoh the stakes were even higher as the entire cosmos depended on the king's successful journey and resurrection. New excavations are revealing more than we've ever known about what the Egyptians believed they would encounter on their afterlife journey. Now, world renowned archaeologist Dr. Zahi Hawass is excavating a mysterious tunnel at the very bottom of Seti's tomb far below the surface of the earth. Join National Geographic on a true Indiana Jones-style quest in which Dr. Hawass will put his own life in jeopardy for the sake of discovery.
