Marinette accidentally drops her history textbook while transformed as Ladybug. Alya, who happened to be at the scene, trying to film Ladybug in action, picks up the book, and speculates that Ladybug could be a Parisian collégienne. Marinette starts to panic when she finds out, and by Tikki's suggestion, brings Alya to visit a new Pharaoh exhibition at the Louvre, in order to try to get the book back. As they arrive, Alix's brother, Jalil Kubdel, is discussing with his father about how one of the exhibitions on display is a resurrection spell. He believes that it could work, and wants to test it out, but Jalil's father claims that such an important historical artifact cannot be misused. Frustrated that his father does not believe him, Jalil is influenced by Hawk Moth and transforms into "The Pharaoh" with Egyptian god powers who intends to bring back Nefertiti using Alya as a sacrifice. In this episode, there was a long line of Ladybugs going back over 5,000 years with Marinette being the latest Ladybug.
