What Happens, Part by Part (Contains Spoilers)
A warning
At the Dursleys' house, a house-elf named Dobby appears and warns Harry not to return to Hogwarts. Dobby ruins a dinner party, and Harry is locked in his room. Ron and his brothers rescue him in a flying car. When Harry and Ron miss the train to school, they fly the car to Hogwarts and crash into the Whomping Willow.
Strange events
The new Defense Against the Dark Arts teacher, Gilderoy Lockhart, is charming but useless. Harry begins hearing a strange voice in the walls. Mrs. Norris, the caretaker's cat, is found petrified, and a message warns that the Chamber of Secrets has been opened. Students fear the “Heir of Slytherin” will attack those with non-magical parents.
Parseltongue
During a dueling club, Harry speaks to a snake in Parseltongue, a rare language linked to Salazar Slytherin. Students suspect he is the Heir. More students are petrified, including Hermione. Harry finds a diary belonging to Tom Riddle, a former student, which shows him a memory of the Chamber being opened fifty years earlier.
Clues
Harry and Ron learn that a giant spider in the Forbidden Forest, Aragog, was blamed long ago, but he is not the monster. A note in Hermione's petrified hand reveals that the monster is a basilisk, a giant snake that kills with its gaze. It moves through the school's pipes. Then Ginny is taken into the Chamber.
The Chamber
Harry and Ron, with a reluctant Lockhart, enter the Chamber through a bathroom haunted by the ghost Moaning Myrtle. Lockhart tries to wipe their memories but erases his own. Harry finds Ginny and meets Tom Riddle, who reveals he is the young Lord Voldemort, using the diary. With help from Dumbledore's phoenix, Fawkes, and the sword of Gryffindor, Harry kills the basilisk and destroys the diary. He then frees Dobby.
