In this Italian costume epic chronicles the exploits of an innocent maiden who lives near Thebes. She is in love with a sculptor but cannot marry him when a high-ranking reveals that he is her father and that she was betrothed at birth to a mentally ill prince slated to soon take over the country. The father then hands down a death sentence for the sculptor, but fortunately he escapes to find the prince, who happens to be a friend of his. There he asks for and is granted a pardon. Time passes and the prince becomes king; meanwhile, the maiden undergoes a ritual purification and changes her name to "Nefertiti." The sculptor is now with a gypsy. Unfortunately, he is again imprisoned by Nefertiti's father who threatens to kill him unless his unwilling daughter marries the new king. After the wedding, the sculptor does a bust of his beloved, and she tells him that while she still loves him, she fears for her husband's mind if she leaves. Her manipulative father is well aware of the king's instability and is hoping that eventually he will have all the power. To get closer, he kills the king's best friend, a rival priest, which pushes the king to suicide. Suddenly Nefertiti becomes queen. With the sculptor's help, she rallies the army and wins her power. In the end, the jilted gypsy gets her revenge by killing Nefertiti's father.
