During the era of Akhenaten, Amenhotep and Nefertiti exchange feelings of admiration. Queen Tiye is surprised by her son's conversion to monotheism, and the Pharaoh issues a decision to execute Mahwah for refusing to prostrate before the god Amun.
Mahwah places the book of Idris on his chest, which saves him from the arrow reaching his heart. The Pharaoh is surprised and issues an order to pardon him. Horemheb has feelings of admiration for Nefertiti. The Pharaoh appoints his crown prince, Amenhotep, as his assistant in government affairs.
Amenhotep III dies after his illness becomes severe, and Tiye seeks to approach the priests to bless the coronation of Amenhotep IV as ruler. Tiye still refuses to marry her son to Nefertiti, so she issues a decision to keep her in her ward.
Tiye resorts to seeking the help of the priests of Amun to perform magic that would make Nefertiti lose her mind in order to stop Amenhotep from marrying her. Tiye is forced to cancel her decision to keep Nefertiti in her ward after her son’s intervention.
Horemheb discovers the plot of the ruler Aziru to entrap Thebes. Tiye is surprised by the failure of the magic she had planned, and she promotes the cupbearer Tutu to become the head of the servants. The priest Anan rejects Amenhotep's marriage to Nefertiti.
The wise man succeeds in convincing Anan and Tiye to allow Amenhotep to marry Nefertiti. Tutu seeks to reach the position of the person responsible for letters in the palace. Amenhotep IV marries Nefertiti.
Ai, the wise man, doubts Tutu because he is of Amurian origin, and Amenhotep refuses to be convinced that Aziru is the one trying to overthrow him. The wise man still has love for Tiye, and Nefertiti informs Amenhotep of her pregnancy.
Tutu marries Rebecca, Aziru's sister, in order to spy on the Pharaoh for him. Tiye discovers that Amenhotep is teaching Smenkhkare and Tutankhamun the teachings of monotheism. Akhenaten begins lessons to educate those close to him about monotheism.
Amenhotep IV declares freedom of belief, his embracing monotheism, and his changing his name to Akhenaten. Tiye's illness becomes severe. Ay continues to help Akhenaten spread the monotheistic religion and asks to marry Tiye.

Rebecca travels to Thebes to stay with her husband, Tutu, and Tiye refuses to immigrate to the new city. The number of immigrants to the monotheistic city increases, and the priest Anan decides to prevent immigration to the new city due to the small number of people who worship the god Amun.
Anan cooperates with Tutu to deliver a poisoned letter to Akhenaten. Rebecca suggests that he inform the Pharaoh that it is poisoned in order to gain his trust. Tutu destroys the letters sent to Akhenaten from Tulip asking for his help to rid them of those occupying their country.
Akhenaten issues a decision to demolish the other temples, and Nefertiti is surprised that the Pharaoh excluded the priests of the god Ptah from his decision. Akhenaten is also surprised by his mother’s visit to the city of Akhetaten, claiming that she has embraced the monotheistic religion.
Akhenaten's decision to share the kingship with Smenkhkare surprises Nefertiti. Tiye convinces her son Akhenaten to marry Smenkhkare to Meritaten, and a distress message from the people of Tulip reaches Anan.
Akhenaten sends his army with Horemheb to liberate Tulip, and Akhenaten obeys his mother by guaranteeing freedom of belief again. Akhenaten decides to appoint Smenkhkare as governor of Thebes in fulfillment of his mother’s desire. Akhenaten decides to marry Tadukhipa.
Horemheb captures Rebecca with a letter from Tutu proving his guilt. Akhenaten marries Tadukhipa. Smenkhkare neglects monotheism, and Horemheb defeats Aziru. Later, Tadukhipa suffers from the effects of poison.
Tutankhamun marries Ankhesenpaaten without Akhenaten's knowledge. Mahwah agrees with Tadukhipa to provide her with medicine in exchange for getting out of Akhetaten, and Aziru and Zaya flee from the Egyptians.
The priests of Amun and the priests of Ptah cooperate to get rid of Akhenaten, who decides to crown Tadukhipa as Queen of Egypt and build a city in her name next to Akhetaten, separated by a door.
Anan's plan to lure Akhenaten to come to Thebes to see the sick Tiye in order to get rid of him succeeds, and Anan's men arrest Akhenaten.
After liberating all the cities that Aziru had occupied, Horemheb returns only to discover that Amun's priests have abducted Akhenaten and his brother, Smenkhkare. Nefertiti is shocked when she learns that Anan killed Akhenaten and his brother.
