While escaping the Egyptians 2,500 years ago, the Persian King Cambyses led his army into the desert and disappeared forever. Despite efforts in the 1930s to discover what happened to him, no clues were found until 1996 when a geologist stumbled on evidence by accident. The Egyptian authorities have suppressed news of these findings until now. The Lost Army Of King Cambyses returns to the site to uncover the truth.
