Harry Potter and the chamber of secrets

Plot

Harry Potter's summer holiday with the Dursleys is not going to plan. The Dursleys have forbidden all of Harry's school possessions. Harry has not yet received any letters from his friends, Ron and Hermione. Finally, on his 12th birthday, Dobby the house elf arrives to warn Harry that he will be in mortal danger if he returns to Hogwarts. Harry is determined to return, as it is the only true home he has ever known, so Dobby destroys the cake for an important dinner party attended by Uncle Vernon's potential client and the client's wife. The Ministry of Magic sends a letter explaining Harry cannot use magic outside of school as he will be expelled. No longer afraid of Harry's potential as a wizard, Uncle Vernon tells Harry he cannot return to Hogwarts and puts bars on Harry's window, trapping his nephew.

Ron and his twin brothers Fred and George rescue Harry and take him to their home in their flying car. Ginny Weasley, Ron's younger sister, is just starting at Hogwarts and is overwhelmed when she meets Harry. After a pleasent month living at the Burrow, Harry and five of the Weasley children head to Platform 9¾ to take the Hogwarts Express back to school. To their shock, Harry and Ron are unable to enter the barrier between platforms 9 and 10 (it is later revealed that Dobby sealed it shut to prevent Harry from returning to Hogwarts). In desperation, they steal the flying car and fly to Hogwarts. They crash into the Whomping Willow, which immediately attacks, damaging the car and snapping Ron's wand in half. The wrecked car then disappears into the Forbidden Forest. Luckily, the two escape expulsion from school.

Events at school take a turn for the worse when the legendary Chamber of Secrets is opened and a monster begins to stalk the castle, petrifying anyone who meets its gaze. According to legend, the Chamber was built by one of the Hogwarts founders, Salazar Slytherin, and can be opened only by his heir, in order to purge Hogwarts of 'all those who were unworthy to study magic' or 'Muggle-borns'. Many suspect Harry to be the heir of Slytherin because, while trying to save another student during a duel against Draco Malfoy, he inadvertently speaks Parseltongue, the ability to talk to snakes and a talent that characteristically belongs to Slytherins. Harry, Ron, and Hermione suspect Draco, Harry's rival, is actually the culprit, but after a careful inquiry, their conjecture proves wrong. As the school year progresses with more attacks, the Ministry arrests Hagrid, thinking he is responsible for the attacks, and suspends Dumbledore for not taking appropriate measures in stabilizing the school's safety. Harry and Ron decide to take control of the situation, their motivation to bring justice and solve the crime intensified by the attack on Hermione.
