The House of Ramesses falters as Tausret relinquishes the throne upon the death of her husband, King Seti. Amenmesse's young son Siptah will become king until her infant son is old enough to rule. Tausret, as Regent, and the king's uncle, Chancellor Bay, hold tight to the reins of power and vie for complete control of the kingdoms. Assassination changes the balance of power, and, seeing his chance, Chancellor Bay attempts a coup...

Tausret's troubles mount as she also faces a challenge from Setnakhte, an aging son of the Great Ramesses who believes Seti was the last legitimate king. If Setnakhte gets his way, he will destroy the House of Ramesses and set up his own dynasty of kings.
