S1, E2: Only a handful of people have ever had the chance to see the Five Chambers high above the Grand Gallery of the Great Pyramid. Now, Zahi decides to go on his final journey to the Five Chambers with the fellows in tow...together they will document the ancient graffiti on the walls of the Chambers, proving Zahi's theory that ancient Egyptians, not slaves, built the Pyramids at Giza. This near-death experience leaves the fellows; Leslie, the executive producer; and, the crew gasping for air. Finally, Zahi will reveal his findings in an exclusive television interview.
