Dedicated Egyptologist Erica Baron is researching a paper about the chief architect to Pharaoh Seti. Soon after her arrival in Cairo, she witnesses the brutal murder of unscrupulous art dealer Abdu-Hamdi, meets a French journalist named Yeon, and is befriended by Akmed Khazzan, who heads the antiquities division of the United Nations. When she journeys to the Valley of the Kings in Luxor to search a tomb reportedly filled with treasures, she finds herself the target of black marketeers determined to keep the riches themselves.

Vincent Canby of the New York Times said the film "never stops talking and never does it make a bit of sense. It's unhinged. If it were a person, and you were trying to be nice, you might say it wasn't itself." He continued, "Mr. Schaffner and Mr. Byrum have effectively demolished what could have possibly been a decently absurd archeological-adventure film. The locations . . . are so badly and tackily used that the movie could have been shot more economically in Queens . . . The performers are terrible, none more so than Mr. Langella, who is supposed to be mysterious and romantic but behaves with all of the charm of a room clerk at the Nile Hilton." In conclusion, he called the film "total, absolute, utter confusion."
Variety described the film as a contemporary version of The Perils of Pauline and called it "an embarrassment," adding "Franklin J. Schaffner's steady and sober style is helpless in the face of the mounting implausibilities." 
Time Out New York thought the film made "striking use of locations" but criticized the "lousy script, uneasy heroine, and weak material." It called it a "clear case of a lame project that only a best selling (ie. heavily pre-sold) novel could have financed" and warned audiences to "avoid" it.
