200 years ago, a young French scientist, Jean-François Champollion, succeeded in doing the impossible: deciphering the code of the hieroglyphs, which had remained silent for over a thousand years. Thanks to this key, an entire civilization buried under the sands of Egypt was reborn... In the south of the country, near Luxor, a palace of hieroglyphs intrigues Egyptologists: the tomb of a priest called Padiamenope, the most monumental in Egypt, larger than those of the pharaohs. An exclusive access to the heart of the archaeological mission of the tomb of Padiamenope "TT 33", of the French Institute of Oriental Archaeology (IFAO), reveals their latest discoveries. Thanks to a unique 3D virtual tour system, this film allows us to plunge into the dark depths and the scorching heat of the tomb and to penetrate the secrets of the priests, scribes, painters, engravers and builders who constructed this extraordinary funerary monument.
