Professor Lampton's work of excavating the tomb of Akhnaton (Ikhnaton) is held up by lack of funds, and Prince Dagmar, scion of a Balkan royal family, finances him with the ulterior motive of robbing the tomb of its treasures. Michael Amory, an artist assisting Lampton, loves Margaret, but believing her to be in love with the prince he departs with Gondo Koro, a Bedouin prophet who knows the location of the tomb. Dagmar sends Millicent, an adventuress, to obtain the information from Michael, and when Dagmar enters the tomb at night Michael surprises him. The thieves wound Michael, but they are captured and he and Margaret are reconciled.
