The Hyksos drive south into the Nile Valley, sweeping all resistance aside. Bebi and Sobekhotep, grandsons of Harrubaal, assume command of the loyal Egyptian army and strive to stem the flood of Hyksos conquest. But even the cities of the south are divided against themselves.

Abdju, an old capital city of Egypt reasserts itself, putting forward a line of kings of its own, and soon the city is at war with Waset, the southern capital of the Nile Valley, as the two cities fight for supremacy in the face of the advancing northern enemy. Caught up in the turmoil of warring nations, the ordinary people of Egypt must fight for their own survival as well as that of their kingdom.
