A formidable secret hidden by a High Priest during the building of the Giza pyramids... an ancient Egyptian ring given by Napoleon to Champollion.

Four thousand years later, an American archeology professor uncovers a hidden chamber in Egypt with a strange Sphinx statue mounted on a carved stone pillar beside an entombed skeleton. Now a special unit of Interpol is trying to recover the stolen artifacts and protect the world from the terrible menace of a secret masonic organization, DOOM.

From the dunes of Saqqara to California, Andalusia and Paris, a frenetic pursuit is engaged.  

Will the secret of the Sphinx be deciphered?
