In ancient Egypt a Princess is loved by a simple Shepherd, to the great displeasure of the King, who orders the offending lover be buried alive, for he had promised his daughter to the builder of the Temple. Breaking a double scarab in two, the shepherd and the Princess each keep a broken half and pledge that their souls will be reunited in death. Centuries later Capt. Harry Paget of the English garrison at the Sudan is enchanted by Grace Leslie, the daughter of Sir Hector Leslie, commander of the garrison.
