Bettany starts her journey at the mouth of the Nile River, boarding her dahabiya and meeting the crew that will guide her the length of the river. She first visits the Cairo Museum and looks at its amazing collection.

Bettany visits a vast desert catacomb where tens of thousands of mummified animals were once left as an offering, tracks down Egypt's lost emblem, the Blue Lotus flower, and finishes at the stunning Dendera temple.

Bettany visits the west bank where, for 500 years, ancient Egyptians buried their pharaohs in the Valley of the Kings. Then, she heads south on the Nile's oldest steamship, SS Sudan, which inspired Agatha Christie to write Death on the Nile.

Bettany reaches the Nile's southernmost stretches. She joins archaeologists at the temple of the crocodile god Sobek, and ends her journey near Egypt's border with Sudan, where Ramesses the Great built the most outrageous of temples.
