In his second year at Hogwarts, Harry Potter ignores warnings from Dobby, a house-elf, and returns to school despite a mysterious threat. Students begin being petrified, and messages on the walls announce that the Chamber of Secrets has been opened. Through an enchanted diary, Harry discovers that Tom Riddle, a memory of Voldemort's younger self, has been controlling Ginny Weasley. When Ginny is taken into the Chamber, Harry descends to rescue her, battling a deadly basilisk with help from Fawkes the phoenix and the Sword of Gryffindor. He destroys the diary, saving Ginny and uncovering dark secrets of Voldemort's past.
