A 5000-years-dead pharaoh (descendant of the REAL Scorpion King) and his favorite concubine quarrel bitterly inside an exhibit hall in a museum in Cairo, about love, hate, and murder--especially his murder of his brother and his and the concubine's son. When gods Isis and Anubis step in, a possibility of reconciliation with each other and the dead reveals itself.
