Movie about a female treasure hunter


The movie was about a female treasure hunter. She was searching a scroll in a buried city somewhere in a desert. The scroll would lead her to some treasure.

I believe there was a flashback in the movie where three knights hide that scroll in that city when it wasn't buried.

It was seen on television in about 2009, and it was in English.

Could it have been an old film you were watching in 2009. If so, perhaps it could be "Sphinx" from 1981.
