We have three brave heroes: treasure seekers Dirk Pitt along with his friend and partner Al Giordino, as well as a doctor from the World Health Organization - the unsurpassed Eva Rojas. All of them were brought together under its languishing hot sun by one of the largest deserts on Earth - the Sahara. Everyone has their own reasons to visit this beautiful, but excessively dangerous world of sand dunes in their own way. Treasure hunters are looking for the Confederate Ironclad Ship "Texas" with a valuable cargo on board, inexplicably trapped under the sand, and the doctor must find the source of an unknown disease by all means. Together they will survive a whole series of adventures, fight off villains, find friendship and true love!
