One day, Mr. Dursley, a prosperous Englishman, is on his way to work when he begins to see some peculiar occurrences. Outside of the Dursleys’ house the same night, Albus Dumbledore, the headmaster of a wizardry school known as Hogwarts, encounters Professor McGonagall, who is also a teacher at Hogwarts, as well as a giant named Hagrid. Dumbledore reveals to McGonagall that a person known as Voldemort is responsible for the deaths of Mr. and Mrs. Potter, as well as the failed attempt to kill their infant son, Harry. A message containing an explanation is left for Harry by Dumbledore in a basket that is placed in front of the Dursley home.
After ten years have passed, Dudley, Harry’s cruel and oppressive tormentor, has taken over the household of his cruel aunt and uncle, the Dursleys. While Dudley is allowed to live a pampered life, Harry is made to sleep in a cupboard beneath the stairs. Everyone gets frightened when the glass that was in front of the boa constrictor exhibit breaks on Dudley’s birthday when they are at the zoo. After some time has passed, Harry is disciplined for this incident.
Harry starts getting these mysterious notes in the mail. They cause Mr. Dursley concern, and despite his efforts to keep Harry away from them, the letters continue to find their way into the home through every available opening. Last but not least, on the evening of Harry’s eleventh birthday, he takes his family and runs away to a remote island cabin. They were awakened at midnight by a loud knock on the door, and Hagrid was already there. Harry receives a letter of acceptance from Hagrid to attend the Hogwarts School of Witchcraft and Wizardry. Harry discovers that the Dursleys have, for his whole life, made an effort to conceal the fact that he is a wizard.
The following day, Hagrid takes Harry shopping in London for items that he will need for school. They begin their adventure by visiting Gringotts, the wizarding bank, where Harry is informed that his parents have provided him with a sizeable inheritance in the form of money. They go shopping on Diagon Alley, which is the main commercial strip for wizards, and it is there that Harry gets measured for his school uniform. Harry spends his money on books, ingredients for potions, and, finally, a magic wand. This wand is a companion to the one Voldemort uses to cast his spells.
After a month has passed, Harry visits the train station and boards the train that will take him to Hogwarts on track nine and three quarters. Harry Potter makes friends with other first-year students on the journey to Hogwarts, including Ron Weasley and Hermione Granger, a Muggle girl who was accepted to the school. The first-year students at the educational institution take turns donning the “Sorting Hat” in order to choose in which residential home they will be placed. Harry, Ron, and Hermione all end up in the more honourable Gryffindor house, despite Harry’s suspicions that they will be placed in the more evil Slytherin house.
Harry Potter finds out early on in the new school year that Professor Snape, his Potions teacher, does not like him. Harry receives reassurance from Hagrid that Snape does not have a valid cause to despise him. Students are instructed to remain on the ground for the first flying lesson on broomsticks because the instructor must tend to an injured pupil called Neville who is being transported to the hospital. Draco Malfoy, a bully who is a member of the Slytherin house, takes Neville’s cherished possession and flies away with it to the top of a tree. Harry pursues him by flying after him. Harry makes a stunning catch after Malfoy has thrown the ball into the air and into the air it continues to travel. This is something that Professor McGonagall sees firsthand. Instead of disciplining Harry, she suggests that he represent Gryffindor in the game of Quidditch, which is a lot like soccer but played on broomsticks. Quidditch is a very popular sport. Malfoy issues an invitation to Harry later that day for a wizard’s duel to take place at midnight. When Malfoy fails to appear at the specified location, Harry comes dangerously close to getting in trouble. While he was trying to conceal himself, he made the unfortunate discovery of a vicious three-headed dog that was guarding a trapdoor in the restricted area of the third floor.
On Halloween, a troll is discovered hiding inside the structure. The students are all led back to their respective dormitories, but Harry and Ron manage to escape and make their way toward Hermione, who is still outside and is oblivious to the troll. They do not realise that they have Hermione and the troll trapped inside the ladies’ restroom together. They are victorious when working together. Hermione makes a fib in order to save Harry and Ron from the consequences of their actions. When Harry competes in his first game of Quidditch, his broom suddenly jerks out of control. Hermione observes that Snape is fixated on Harry and murmuring a curse to himself. She comes to the conclusion that he is jinxing Harry’s broom, and as a result, she sets fire to Snape’s garments. After regaining command of the broom, Harry executes a brilliant strategy to clinch the victory in the Quidditch match.
Harry obtains the cloak that his father used to become invisible for Christmas, and he uses it to go about the campus undetected late at night. He unearths the Mirror of Erised, a relic that reveals a person’s innermost aspirations to anybody who gazes into it. When Harry looks in it, he sees a picture of his parents who are still living. Following the holiday, Harry, Ron, and Hermione start to investigate the unexplained connection between a theft at Gringotts and the three-headed guard dog. They discover that the dog is guarding the Sorcerer’s Stone, which is capable of providing its possessor with endless life and a limitless supply of wealth. The Sorcerer’s Stone was previously owned by Dumbledore’s former business partner, Nicolas Flamel.
A few weeks later, Hagrid is playing poker when he wins a dragon egg as a prize. Harry, Ron, and Hermione decide to get in touch with Ron’s older brother, who is a dragon expert, because it is against the law to own dragons. They make preparations to get rid of the dragon, but they are discovered. Gryffindor loses 150 points and receives a heavy punishment because of Harry, Ron, and Hermione’s actions. In addition, as part of their punishment, they will have to accompany Hagrid into the magical forest to investigate who is responsible for the recent deaths of unicorns. In the middle of the woods, Harry stumbles upon a masked man who is imbibing unicorn blood. The man makes an attempt to attack Harry, but the boy is saved by a helpful centaur who reveals to him that the person who tried to attack him was Voldemort. In addition, Harry discovers that it was Voldemort who was attempting to steal the Sorcerer’s Stone all along.
Harry makes the decision that in order to defeat Voldemort, he needs locate the stone first. That same night, he, Ron, and Hermione went to the prohibited corridor on the third floor of the building. They are able to avoid being caught by the guard dog and do a number of remarkable tasks as they go closer and closer to the stone. In the end, Harry comes face to face with Quirrell, who tells him that he must sacrifice himself. Quirrell forces Harry to look into the Mirror of Erised and then tells him to describe what he sees. Quirrell is aware that Harry has a strong desire to locate the stone. At that precise moment, Harry not only sees himself with the stone in his pocket, but he also has the sensation of having the stone in his pocket. On the other hand, he mentions to Quirrell that he notices something else. A voice reveals to Quirrell that the youngster has been lying to him and asks to have a face-to-face conversation with Harry. When Quirrell takes off his turban, the visage of Voldemort that is carved into the back of his head is exposed. Quirrell is instructed to kill Harry by Voldemort, who has taken possession of his body, but when Quirrell comes into contact with Harry, he suffers severe burns. A struggle ensues and Harry passes out.
When Harry finally comes to, he is with Dumbledore in the medical facility where he was treated. Dumbledore explains to Harry that he was only in the nick of time to save him from Quirrell. He continues by saying that he and Flamel have come to the conclusion that the stone must be destroyed. Harry makes his way to the end-of-the-year celebration, where Slytherin is celebrating its seventh consecutive triumph of the house championship cup. Harry watches as Slytherin raises its glass in jubilation. Gryffindor was awarded the House Cup as a result of Dumbledore’s speech, in which he credited many of the remaining points to Gryffindor for the achievements of Harry and his friends. Harry Potter makes his way back to London to spend the summer with his aunt and uncle Dursley.
