Harry Potter and The Philosopher's Stone - Synopsis - Plot

Plot

Before the start of the novel, Voldemort, considered the most evil and powerful dark wizard in history, kills Harry's parents but mysteriously vanishes after trying to kill the infant Harry. While the wizarding world celebrates Voldemort's downfall, Professor Dumbledore, Professor McGonagall and Rubeus Hagrid place the one year-old orphan in the care of his Muggle (non-wizard) uncle and aunt: Vernon and Petunia Dursley.

For ten years, they and their son Dudley neglect, torment and abuse Harry. Shortly before Harry's eleventh birthday, a series of letters addressed to Harry arrive, but Vernon destroys them before Harry can read them. To get away from the letters, Vernon takes the family to a small island. As they are settling in, Hagrid bursts through the door to tell Harry what the Dursleys have kept him from finding out: Harry is a wizard and has been accepted at Hogwarts.

Hagrid takes Harry to Diagon Alley, a magically-concealed shopping precinct in London, where Harry is bewildered to discover how famous he is among wizards as "the boy who lived". He also finds that he is quite wealthy, since a bequest from his parents has remained on deposit at Gringotts Wizarding Bank. Guided by Hagrid, he buys the books and equipment he needs for Hogwarts, as well as Hedwig the owl. At the wand shop, he finds that the wand that suits him best is the twin of Voldemort's; both wands contain feathers from the same phoenix.

A month later Harry leaves the Dursleys' home to catch the Hogwarts Express from King's Cross railway station. There he meets the Weasley family, who show him how to pass through the magical wall to Platform 9¾, where the train is waiting. While on the train Harry makes friends with Ron Weasley, who tells him that someone tried to rob a vault at Gringotts. During the ride they meet Hermione Granger. Another new pupil, Draco Malfoy, accompanied by his sidekicks Vincent Crabbe and Gregory Goyle, offers to advise Harry, but Harry dislikes Draco's arrogance and prejudice.

Before the term's first dinner in the school's Great Hall, the new pupils are allocated to houses by the magical Sorting Hat. Before it is Harry's turn, he catches Professor Snape's eye and feels a pain in the scar Voldemort left on his forehead. When it is Harry's turn to be sorted, the Hat wonders whether he should be in Slytherin, but when Harry objects, the Hat sends him to join the Weasleys in Gryffindor. While Harry is eating, he questions Percy Weasley about Snape.

After a terrible first Potions lesson with Snape, Harry and Ron visit Hagrid, who lives in a rustic house on the edge of the Forbidden Forest. There they learn that the attempted robbery at Gringotts happened the day Harry withdrew money. Harry remembers that Hagrid had removed a small package from the vault that was broken into and searched.

During the new pupils' first broom-flying lesson, Neville Longbottom breaks his wrist, and Draco takes advantage to throw the forgetful Neville's fragile Remembrall high in the air. Harry gives chase on his broomstick, catching the Remembrall inches from the ground. Professor McGonagall dashes out and appoints him as the new Seeker for the Gryffindor Quidditch team.

When Draco tricks Ron and Harry, accompanied by Neville and Hermione Granger, into a midnight excursion, they accidentally enter a forbidden corridor and find a huge three-headed dog. The group hastily retreats, and Hermione notices that the dog is standing over a trap-door. Harry concludes that the monster is guarding the package Hagrid retrieved from Gringotts.

After Ron criticises Hermione's ostentatious proficiency in Charms, she hides in tears in the girls' toilet. At the Halloween Night dinner, Professor Quirrell hastily reports that a troll has entered the dungeons. While everyone else returns to their dormitories, Harry and Ron rush to warn Hermione. The troll corners Hermione in the toilet but when Harry sticks his wand up one of its nostrils, Ron uses the levitation spell to knock out the troll with its own club. Afterwards, several professors arrive and Hermione takes the blame for the battle and becomes a firm friend of the two boys.

The evening before Harry's first Quidditch match, he sees Snape receiving medical attention from Filch for a bite on his leg by the three-headed dog. During the game, Harry's broomstick goes out of control, endangering his life, and Hermione notices that Snape is staring at Harry and muttering. She dashes over to the Professors' stand, knocking over Professor Quirrell in her haste, and sets fire to Snape's robe. Harry regains control of his broomstick and catches the Golden Snitch, winning the game for Gryffindor. Hagrid refuses to believe that Snape was responsible for Harry's danger, but lets slip that he bought the three-headed dog, and that the monster is guarding a secret that belongs to Professor Dumbledore and someone called Nicolas Flamel.

Harry and the Weasleys stay at Hogwarts for Christmas, and one of Harry's presents, from an anonymous donor, is an Invisibility Cloak owned by his father. Harry uses the Cloak to search the library's Restricted Section for information about the mysterious Flamel, has to evade Snape and Filch after an enchanted book shrieks an alarm, and slips into a room containing the Mirror of Erised, which shows his parents and several of their ancestors. Harry becomes addicted to the Mirror's visions and is rescued by Professor Dumbledore, who explains that it shows what the viewer most desperately longs for.

When the rest of the pupils return for the next term, Draco plays a prank on Neville, and Harry consoles Neville with a sweet. The collectible card wrapped with the sweet identifies Flamel as an alchemist. Hermione soon finds that he is a 665-year-old man who possesses the only known Philosopher's Stone, from which can be extracted an elixir of life. A few days later Harry notices Snape sneaking towards the outskirts of the Forbidden Forest. There he half-hears a furtive conversation about the Philosopher's Stone, in which Snape asks Professor Quirrell if he has found a way past the three-headed dog and menacingly tells Quirrell to decide whose side he is on. Harry concludes that Snape is trying to steal the Stone and Quirrell has helped prepare a series of defences for it, which was an almost fatal mistake.

The three friends discover that Hagrid is raising a baby dragon, which is against wizard law, and arrange to smuggle it out of the country around midnight. Draco arrives, hoping to raise the alarm and get them into trouble, and goes to tell Professor McGonagall. Although Ron is bitten by the dragon and is sent to the infirmary, Harry and Hermione spirit the dragon safely away. However, they are caught, and Harry loses the Invisibility Cloak. As part of their punishment, Harry, Hermione, Draco, and Neville (who, trying to stop Harry and Hermione after hearing what Draco had been saying, had been caught by McGonagall as well) are compelled to help Hagrid to rescue a badly-injured unicorn in the Forbidden Forest. They split into two parties, and Harry and Draco find the unicorn dead, surrounded by its blood. A hooded figure crawls to the corpse and drinks the blood, while Draco screams and flees. The hooded figure moves towards Harry, who is knocked out by an agonising pain spreading from his scar. When Harry regains consciousness, the hooded figure has gone and a centaur, Firenze, offers to give him a ride back to the school. The centaur tells Harry that drinking a unicorn's blood will save the life of a mortally injured person, but at the price of having a cursed life from that moment on. Firenze suggests Voldemort drank the unicorn's blood to gain enough strength to make the elixir of life from the Philosopher's Stone, and regain full health by drinking that. On his return, Harry finds that someone has slipped the Invisibility Cloak under his sheets.

A few weeks later, while relaxing after the end-of-session examinations, Harry suddenly wonders how something as illegal as a dragon's egg came into Hagrid's possession. The gamekeeper says he was given it by a hooded stranger who bought him several drinks and asked him how to get past the three-headed dog, which Hagrid admits is easy – music sends it to sleep. Realising that one of the Philosopher's Stone's defences is no longer secure, Harry goes to inform Professor Dumbledore, only to find that the headmaster has just left for an important meeting. Harry concludes that Snape faked the message that called Dumbledore away and will try to steal the Stone that night.

Covered by the Invisibility Cloak, Harry and his two friends go to the three-headed dog's chamber, where Harry sends the beast to sleep by playing a flute given to him by Hagrid for Christmas. After lifting the trap-door, they encounter a series of obstacles, each of which requires special skills possessed by one of the three, and one of which requires Ron to sacrifice himself in a game of wizard's chess. In the final room Harry, now alone, finds Quirrell rather than Snape. Quirrell admits that he let in the troll that tried to kill Hermione on Halloween, and that he tried to kill Harry during the first Quidditch match but was knocked over by Hermione. Snape had been trying to protect Harry and suspected Quirrell. Quirrell serves Voldemort and, after failing to steal the Philosopher's Stone from Gringotts, allowed his master to possess him in order to improve their chances of success. However the only other object in the room is the Mirror of Erised, and Quirrell can see no sign of the Stone. At Voldemort's bidding, Quirrell forces Harry to stand in front of the Mirror. Harry feels the Stone drop into his pocket and tries to stall. Quirrell removes his turban, revealing the face of Voldemort on the back of his head. Voldemort/Quirrell tries to grab the Stone from Harry, but simply touching Harry causes Quirrell's flesh to burn. After further struggles Harry passes out.

He awakes in the school hospital, where Professor Dumbledore tells him that he survived because his mother sacrificed her life to protect him, and Voldemort could not understand the power of such love. Voldemort left Quirrell to die, and is likely to return by some other means. Dumbledore had foreseen that the Mirror would show Voldemort/Quirrell only themselves making the elixir of life, as they wanted to use the Philosopher's Stone; Harry was able to see the Stone in the Mirror because he wanted to find it but not to use it. The Stone has now been destroyed.

Harry returns to the Dursleys for the summer holiday, but does not tell them that under-age wizards are forbidden to use magic outside Hogwarts.

After ten years, Harry became an eleven year-old boy. The Dursleys have kept the truth about Harry's parents from him, but it is revealed in the form of Rubeus Hagrid, who tells Harry that he is a wizard and has been accepted at Hogwarts for the autumn term. Harry takes the train to Hogwarts from King's Cross Station. On the train, Harry sits with and quickly befriends Ron Weasley; the two are also briefly visited by Neville Longbottom and Hermione Granger. Later on in the journey, Malfoy comes into Harry and Ron's compartment with his friends Crabbe and Goyle and introduces himself. After Ron laughs at Draco's name, Draco offers to help Harry distinguish the wrong sort of wizards, but Harry declines.

Upon arrival, the Sorting Hat places Harry, Hermione, Neville and Ron into Gryffindor House, one of the school's four houses, while Draco and his cronies are placed in Slytherin. After a broom-mounted game to save Neville's Remembrall, Harry joins Gryffindor's Quidditch team as their youngest Seeker in over a century.

Shortly after school begins, Harry and his friends hear that someone broke into a previously emptied vault at the wizarding bank, Gringotts. The mystery deepens when they discover a monstrous three-headed dog, Fluffy, who guards a trapdoor in the forbidden third floor passageway. On Halloween, a troll enters the castle and traps Hermione in one of the girls' lavatories. Harry and Ron rescue her, but are caught by Professor McGonagall. Hermione defends the boys and takes the blame, which results in the three becoming close friends.

Harry's broom becomes jinxed during his first Quidditch match, nearly resulting in Harry falling from a great height. Hermione believes that Professor Snape has cursed the broom and distracts him by setting his robes on fire, allowing Harry to catch the Golden Snitch and win the game for Gryffindor.

At Christmas, Harry receives his father's Invisibility Cloak from an unknown source. Later, he discovers the Mirror of Erised, a strange mirror that shows Harry surrounded by his parents and the extended family he never knew. Later, Harry learns that Nicolas Flamel is the maker of the Sorcerer's Stone, a stone that gives the owner eternal life.

Harry sees Professor Snape interrogating Professor Quirrell about getting past Fluffy, seemingly confirming the suspicion that Snape is trying to steal the Philosopher's Stone in order to restore Lord Voldemort to power. The trio discover that Hagrid is hiding a dragon egg, which hatches; since dragon breeding is illegal, they convince Hagrid to send the dragon to live with others of its kind. Harry and Hermione are caught returning to their dormitories after sending Norbert off and are forced to serve detention with Hagrid in the Forbidden Forest. In the forest, Harry sees a hooded figure drink the blood of an injured unicorn. Firenze, a centaur, tells Harry that the hooded figure is Voldemort.

Hagrid accidentally tells Harry, Ron, and Hermione how to get past Fluffy; and they rush to tell the headmaster, Albus Dumbledore, what they know, only to find that he has been called away from the school. Convinced that Dumbledore's summons was a red herring to take him away while the Philosopher's Stone is stolen, the trio set out to reach the Stone first. They navigate a series of complex magical challenges set up by the school's faculty, and at the end of these challenges, Harry enters the inner chamber alone, only to find that it is the timid Professor Quirrell, not Snape, who is after the Stone. The final challenge protecting the Stone is the Mirror of Erised. Quirrell forces Harry to look into the mirror to discover where the Stone is hidden; and Harry successfully resists, and the Stone drops into his own pocket. Lord Voldemort reveals himself: he has possessed Quirrell and appears as a ghastly face on the back of Quirrell's head. Quirrell tries to attack Harry, but merely touching Harry proves to be agony for him. Voldemort flees and Quirrell dies as Dumbledore arrives back in time to save Harry.

As Harry recovers, Dumbledore confirms that Lily had died while trying to protect Harry as an infant. Her pure, loving sacrifice provides her son with an ancient magical protection against Voldemort's lethal spells. Dumbledore also explains that the Philosopher's Stone has been destroyed to prevent Voldemort from ever using it. He then tells Harry that only those who wanted to find the Stone, but not use it, would be able to retrieve it from the mirror, which is why Harry could acquire it. When Harry asks Dumbledore why Voldemort attempted to kill him when he was an infant, Dumbledore promises to tell Harry when he is older.

At the end-of-year feast, where Harry is welcomed as a hero. Dumbledore gives a few last-minute additions, granting enough points to Harry, Ron, Hermione, and Neville Longbottom for Gryffindor to win the House Cup, ending Slytherin's six-year reign as house champions.
