In Egypt, Clea must break the Sphinx's curse! Clea is propelled into ancient Egypt to help Nour, the Pharaoh's daughter. The little princess is desperate because Nafretiri, her older sister, is very ill. According to an old prophecy, if the girl dies before her sixteenth birthday, Egypt will fall into the hands of its worst enemies, the Babylonians. Even the greatest magician in the kingdom can do nothing to cure her. There is only one hope: to find the magic potion of Neith, the goddess of healing. According to legend, it is hidden in a secret cave, whose hiding place only the Sphinx knows. Clea and Nour decide to set off in search of the mythical creature to try to save Nafretiri and the kingdom of Egypt.
