A myth, a legend, a chamber. These elements are all in Harry Potter and the Chamber of Secrets. It all begins with Harry at number 4 Privet Drive with the Dursleys. It’s the summertime and Harry is feeling miserable. The year before, Harry attended at Hogwarts School of Witchcraft and Wizardry and it changed his life forever. That was when he found out he was a wizard, lived through Voldemort’s killing curse, and made the two best friends he would ever have.
His horrible uncle, aunt, and cousin are keeping him trapped in the house with no one to keep him company but his faithful snow-white owl, Hedwig. He is afraid that the magical life he once had at Hogwarts was all just a dream. His summer is going down the drain—until a little house elf from the magical world appears in his room. Dobby, the house elf, warns Harry that danger awaits him back at Hogwarts. No matter how charming Dobby may seem, Harry doesn’t want to believe him. Hogwarts was his first real home where he finally had real friends. Dobby causes destruction downstairs intentionally to discourage Harry from going back. But why? Harry’s horrid Uncle Vernon is outraged and locks Harry in his room.
In the middle of the night, Harry hears a noise outside. It is his faithful friend Ron Weasley and his twin brothers, Fred and George in a flying Ford Anglia car! Harry escapes from Privet Drive and they fly to the Burrow, the Weasley’s home. Mrs. Weasley is delighted to see Harry in the morning, though she is upset with her sons for sneaking out in the night. Ginny Weasley, Ron’s sister, is also very thrilled to see Harry, but in a bashful way. The Weasleys and Harry go to Diagon Alley to buy their Hogwarts materials. In Diagon Alley, they unite with Harry’s other best friend, Hermione Granger. They also unluckily bump into Draco Malfoy and his father, Lucius. There is a lot of tension between Mr. Weasley and Lucius Malfoy. Harry also meets Gilderoy Lockhart, his vain Defense Against the Dark Arts teacher. Harry and the Weasleys set off to the Hogwarts Express station. Harry and Ron can’t enter the station so they ride Ron’s Ford Anglia up in the clouds, following the Hogwarts Express, later earning Ron a noisy Howler letter from his mother scolding him.
Harry and Ron arrived at Hogwarts safely, though messily, earning them detention. A few days later, Quidditch practices start. Draco Malfoy is the new seeker on the Slytherin team. Draco insults Hermione by calling her a “Mudblood” which insults her Muggle, or non-magical human ancestry. After the practice, Harry hears an eerie voice in the corridors and soon after sees the caretaker’s cat petrified and hung up next to the wall where someone wrote with blood, “The Chamber has been opened. Enemies of the heir beware.” Harry, Ron, and Hermione are shocked. What does this mean? They investigate and find out that fifty years ago a chamber at Hogwarts was opened and a student was murdered. During the Quidditch game, Harry gets smacked by a magical ball that knocks him off his broom. He is brought to the hospital wing and sees a younger first year that has been petrified. When Harry is healed, he realises he can talk Parseltongue to snakes. Everyone is afraid of him because only the heir of Slytherin had the ability to talk to snakes. Later, more students and even a ghost were petrified.
Harry is confused. He needs to learn the truth. Harry, Ron, and Hermione are fixed on solving the mystery. They brew up a complicated potion called the Polyjuice potion which turns someone into a different person. Harry and Ron transform into Malfoy’s buddies to try to squeeze the truth out of him. It turns out Malfoy isn’t the heir of Slytherin. For a while afterwards, there aren’t any more attacks until Harry finds a diary. He writes in it and someone writes back. Harry is shown Tom Riddle, a teenage boy who accused Hagrid, Harry’s giant friend, of opening the Chamber of Secrets. Harry doesn’t know what to make of this. He and Ron go down to Hagrid’s hut to investigate and ask him some questions, but when they arrive at the hut, Lucius Malfoy and Cornelius Fudge, the Minister of Magic, make Dumbledore and Hagrid leave Hogwarts. Before Hagrid leaves, he tells Harry and Ron to follow the spiders that were crawling around Hogwarts. Harry and Ron and lead into the forest where they meet Aragog, Hagrid’s huge spider friend. They learn that Hagrid did not open the Chamber of Secrets and the monster that killed the girl was not a spider. They escape from the hungry spiders just to find Hermione has turned to stone. Harry and Ron find a piece of paper stuck in Hermione’s hand. It is a page from a library book that talks about a snake-like monster called a basilisk that turns people to stone. Before they get a chance to tell anyone about what they have learned, the professors say that Ginny Weasley has been taken into the Chamber.
Harry, Ron, and Lockhart (he joins them) go into the girl’s bathroom and enter the Chamber through a secret passageway. A short while into the passageway, Lockhart injures himself so Ron stays behind with him. Harry goes forward, alone. He enters the Chamber by whispering something in Parseltongue. He sees Ginny Weasley’s still body on the far side of the Chamber. Harry sees Tom Riddle next to her. Tom is actually the preserved younger version of Voldemort. There beside Tom is the basilisk. Dumbledore’s pheonix and Gryffindor sword comes to Harry’s aid. He kills the basilisk with the sword and stabs the diary, where Tom Riddle was being preserved, with the basilisk tooth. Ginny wakes up at that moment. It turns out that Ginny was being possessed by Voldemort through the diary and she was the one who wrote the bloody message on the wall. Harry emerges from the chamber with Ginny, safely. He explains his experience to Dumbledore. Harry is a hero. He demolished Tom Riddle. Hermione is cured, and so are all the rest of the petrified people. Harry goes home for the summer, hoping to see his best friends soon, awaiting the next year at Hogwarts. All was well.
