Harry Potter is in his second year of Hogwarts School of Witchcraft and Wizardry. He is visited by a house-elf named Dobby and warned not to go back to Hogwarts. Harry ignores his warning, and returns. He is still famous, although still disliked by Snape, Malfoy, and the rest of the Slytherins. But then, strange things start to happen. People are becoming petrified, and no-one knows what is doing it. Harry keeps hearing a voice.. a voice which seems to be coming from within the walls. They are told the story of the Chamber of Secrets. It is said that only Salazar Slytherin's true descendent will be able to open it. Harry, it turns out, is a Parsel-tongue. This means that he is able to speak/understand snakes. Everyone thinks that it's him that has opened the Chamber of Secrets because that is what Slytherin was famous for.
