Zachary expects to be bored completely when he is forced to join his parents and his eccentric great-aunt on a visit to a museum exhibit about ancient Egypt. But Great-Aunt Allie, who is fascinated by how Egypt once was, soon strays from the group and enters a door marked STAFF ONLY. DO NOT ENTER. When Zachary goes to look for her, his day gets more interesting -- he and his great-aunt have somehow traveled back in time!
