THE CHAMBER OF SECRETS HAS BEEN OPENED. ENEMIES OF THE HEIR...BEWARE
After returning from Hogwarts, Harry Potter is grounded from going to Hogwarts after ruining the Dursley family's chance to go on vacation. Luckily, Harry Potter's friends, Ron, Fred, and George come and break him out of the house to take him to Hogwarts with their dad's flying car.
Harry stays at the Weasley's house until the next year of Hogwarts begins. When the next year began, the Platform 9 and 3/4 denied access to him and Ron, so they used the car to go to Hogwarts but get in a lot of trouble after being spotted by Muggles and hitting the Whomping Willow. (More like being hit by the Whomping Willow.)
At Hogwarts, Harry, Ron, and Hermione find the janitor's cat, Mrs. Norris, petrified. A warning message is written on the wall next to Mrs. Norris and displays, "THE CHAMBER OF SECRETS HAS BEEN OPENED. ENEMIES OF THE HEIR...BEWARE." The message also appears to be written in blood.
Students start getting petrified and the Golden Trio try to find out who or what is causing the petrification outbreak. Then Harry finds "Tom Riddle's Diary" that has a person inside of it. The Golden Trio keeps searching, but one day, Hermione gets petrified. Luckily, Hermione had found out what was causing the outbreak. A Basilisk.
Ron's sister, Ginny, is kidnapped to the Chamber and Ron and Harry finally find where the Chamber is and rushes to save her. Tom Riddle is waiting in the Chamber and can control the Basilisk. He unleashes the Basilisk, and Harry fights it with a sword that he found in the Sorting Hat that a Phoenix dropped for him. He kills the Basilisk and Tom by destroying his diary.
Harry Potter saves Ginny, and the teachers find a cure for the petrified people. Everyone stays at school for a little bit more until they leave for the Summer, on the Hogwarts Express, and that ends the story of "Harry Potter and the Chamber of Secrets."
