Tutankhamen is dead and his grieving widow tries to rule alone, but her grandfather Ay has not destroyed the former kings just so he can be pushed aside. Presenting the Queen and General Horemheb with a fait accompli, the old Vizier assumes the throne of Egypt and rules with a hand of hardened bronze. His adopted son, Nakhtmin, will rule after him and stamp out the last remnants of loyalty to the former kings.

Scarab was sister to three kings and will not give in to the usurper and his son. She battles against Ay and his legions under the command of General Horemheb and aided by desert tribesmen and the gods of Egypt themselves. The final confrontation will come in the rich lands of the Nile delta where the future of Egypt will at last be decided.
