To the ancient Egyptians, life after death was a high-stakes underworld journey fraught with terrifying obstacles: fiery lakes of death, battles with monsters, and ultimately eternal death or resurrection with the sun.

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. Sahi Hawass is excavating a mysterious tunnel at the very bottom of Seti's tomb--far below the surface of the earth.
