The mystery takes place on a cruise ship while sailing on the Nile. An ancient Egyptian pharaoh's secret tomb and treasure has been discovered. Because of its extraordinary value, it has been named the "Eighth Wonder of the World." A cast of bizarre international characters assembles to view it: a scheming professor, a voluptuous princess, a daffy housekeeper, a slick lounge lizard, an astute writer and a dealer in exotic antiques. Suddenly, gunshots ring out! The archeological wonder becomes the focus of murder. Heated interrogations, shocking revelations and hilarious banter eventually give way to the dramatic realization of whodunit. When the killer is caught, the ancient gods of Egypt can rest easily ... or can they?
