Harry Potter and the Goblet of Fire

Harry, Ron and Hermione enter their fourth year at Hogwarts. After having a strange dream of the Dark Lord and his Death Eaters, Harry Potter awakes at the Weasleys' house where they shortly depart for the 422nd Quidditch World Cup. After the match, the camp is attacked by Death Eaters. The three later arrive at Hogwarts, where they find that the magical school will be hosting a legendary event called the Triwizard Tournament, in which one wizard each from two rival schools and Hogwarts will compete in three dangerous tasks. When the schools of Beauxbatons and Durmstrang, the rival schools, arrive, the rules are announced. Meanwhile, Alastor "Mad Eye" Moody arrives at Hogwarts at the request of Dumbledore to be the new Defence Against the Dark Arts teacher. Moody is a very eccentric man, noted for his paranoia and his wildly roaming "mad eye". People over seventeen who are interested must insert their name into the Goblet of Fire, and those chosen will be the Champions of their respective school. Three champions' names come out of the Goblet of Fire, Cedric Diggory from Hogwarts, Viktor Krum from Durmstrang and Fleur Delacour from Beauxbatons, and then the goblet unexpectedly produces a fourth, Harry Potter, although he is an under-age fourth year who never entered. Although Harry insists that he did not enter his name, his selection prompts a certain amount of jealousy and suspicion on part of his fellow students - including Ron, who believes that Harry is attempting to make himself the centre of attention again. This causes a brief period of resentment and estrangement between the two friends (including Ron swearing, telling Harry to piss off!), which is soon healed, however. Dumbledore tells Alastor to keep an eye on Harry, without him knowing it.

The Tournament begins with the first event, in which the four champions must each battle a dragon to retrieve a golden egg. Upon using the Accio spell to summon his broom, he flies out of the arena. The dragon breaks free of its chain and chases Harry through the Hogwarts grounds, where it runs into a stone bridge and falls dead. Harry gets the egg, which, when opened, will reveal a clue about the second task. When Harry opens it, though, only a horrible screeching is heard. They are soon informed of the Yule Ball, a Christmas ball held during the Triwizard Tournament. Ron and Harry find it hard to get dates to the ball, but finally get the Patil twins to join them, while Hermione goes with Viktor Krum, stunning everyone with her suddenly beautiful appearance at the ball. Ron is so jealously enraged at seeing Hermione with Krum (formerly his idol) that he attacks her and accuses her of "fraternizing with the enemy". The ensuing argument leaves Hermione in tears (in the film version only).

Cedric Diggory, the other Hogwarts champion, informs Harry to submerge the egg in water and open it. There he will hear the clue. Harry does as told in the prefects' enormous collective bath. The clue mentions that merpeople have taken something of Harry's and that they must retrieve it from the Black Lake. Just as the three are trying to find a way to breathe underwater, Ron and Hermione are called to McGonagall's office. Neville tells Harry about gillyweed, which, if eaten, can let you grow webbed hands and feet and gills. During the second task, Harry follows a mermaid to where they have chained Ron, Hermione, Cho Chang, and Fleur's sister. Cho Chang is retrieved by Cedric, Victor, the Durmstrang champion, takes Hermione. Harry takes both Ron and Fleur's sister, since she did not show up.

Finally, the third task arrives. A huge maze has been set up, in the center of which is the Triwizard Cup. The first to touch the cup wins the task. Dumbledore allows Harry and Cedric to be led into the woods first, because they both received first and second place in the previous task. Both Cedric and Harry grab the cup at the same time. The cup, which is actually a portkey, sends the two to a graveyard, where Wormtail appears with a form of Voldemort. Upon command, Wormtail kills Cedric and binds Harry to a tombstone. Wormtail performs a spell over a burning cauldron and drops Voldemort into it. A fully revived Voldemort emerges from it and summons the Death Eaters with the Dark Mark. After explaining to them how he lost his powers to Harry, he duels Harry Potter, in which their spells join in a chain. Harry breaks the chain and gets Cedric's body. After grabbing the cup again, he is transported back to the school where everyone learns that the Dark Lord is back and has killed Cedric. Mad-Eye Moody takes Harry to his office in order to help Harry calm down. Moody suddenly starts to change his appearance when he learns that he has run out of Polyjuice Potion. Moody tells Harry that it was he who told Hagrid to lead Harry and Cedric into the woods first. Moody also reveals that it was he who told Cedric to open the egg underwater and that he gave Neville the book that led him straight to discovering gillyweed in it. Harry realizes that Moody put his name in the Goblet of Fire and that he bewitched Krum. As Moody is about to kill Harry, Dumbledore, Snape, and McGonagall burst in the room and save Harry. Dumbledore makes Moody admit that he is an imposter and that the real Moody is locked in a chest. The imposter rapidly changes from appearing like Moody to his own appearance, Barty Crouch Jr, a Death Eater working for Voldemort. The tournament ends and the other schools depart.

Harry Potter and the Prisoner of Azkaban

It opens at the Dursleys' home where Harry Potter (Daniel Radcliffe) lives and is staying, as usual, during the summer holidays. Uncle Vernon's (Richard Griffiths) sister Marge (Pam Ferris) comes to visit and treats Harry with general contempt. She viciously insults him and his parents, angering Harry who unwittingly uses his innate magical powers to cause her to inflate, and float off, out of the Dursleys' house and into the twilight. Harry flees the Dursleys' home, furious. At first he walks with determination but soon grinds to a stop as he realizes he hasn't anywhere to go. He sits down at the edge of the road with his trunk. His surroundings stir as the wind picks up and a street lamp flickers above him. A jet black dog emerges from the bushes opposite, growling at him and he raises his wand. At that instant however, the eccentric Knight Bus, for lost witches or wizards, makes a sharp appearance and escorts Harry on a wacky journey to the wizards' pub 'The Leaky Cauldron.' While there, Harry learns that Sirius Black (Gary Oldman), an alleged supporter of Lord Voldemort, the dark wizard, has escaped from Azkaban prison. Harry must meet the Minister of Magic Cornelius Fudge (Robert Hardy) and he fears expulsion from Hogwarts for his using of under-age magic out of school. However, the matter is surprisingly dropped as "...the Ministry doesn't send students to Azkaban for blowing up their aunts." While at The Leaky Cauldron Harry also reconvenes with his two best friends, Ron Weasley (Rupert Grint) and Hermione Granger (Emma Watson), and the rest of the Weasley family. Mr. Arthur Weasley (Mark Williams) pulls Harry to one side to warn him about Sirius Black. He suggests that Harry needs to be cautious of Sirius Black due to his allegiance with Voldemort. He believes that Harry is the only thing which stands in the way of Voldemort returning to power and that it is on this premise that Sirius Black has escaped from Azkaban. To find and kill Harry Potter.

Harry, Ron and Hermione board the train to Hogwarts, discovering in their compartment the sleeping Professor Remus Lupin (David Thewlis) who is to be the new 'Defence Against the Dark Arts' teacher. Harry airs his concerns about Black's escape and his possible objective to Ron and Hermione. Tension builds during their discussion however as the train is stopped on a bridge and the lights pop out in each cabin. Ron peers out of the window, concerned that "...there is something out there." The train is violently jolted and a great cold descends around them, ice creeping over the windows. In the corridor outside, a scary dark creature slowly appears, floating towards them. It opens the door to their cabin and begins to engage frighteningly with Harry, sucking at his whole body. The sleeping teacher suddenly wakes, stands up, and repels the creature with a very bright white light emanating from his wand. Harry faints. On his coming round Lupin gives him chocolate to eat and explains that the creature is a 'Dementor' which drains happiness from anything it approaches. The Dementors ordinarily guard the wizard prison, 'The Prison of Azkaban' but are out searching for the escapee Black, and entered the train looking for him. Harry heard a woman screaming during the ordeal, but no one else heard it.

As Harry begins his third year at Hogwarts we learn of some significant changes. Alongside the official announcement of the formerly encountered, new Defence Against the Dark Arts teacher, Professor Lupin. Rubeus Hagrid (Robbie Coltrane), the groundsman, becomes additionally a professor of 'Care of Magical Creatures.' Also, Hermione seems to be taking nearly twice as many classes as everyone else, including some which are taught simultaneously.

During a Divination class, Professor Trelawney (Emma Thompson) foresees Harry's death in the tealeaves of his cup, which form the shape of a 'Grim' or large dog. In tealeaf reading this symbolises death. In Hagrid's first class, Draco Malfoy (Tom Felton) deliberately provokes Buckbeak, a Hippogriff, into attacking and injuring him. Draco's father, Lucius Malfoy, a powerful Ministry of Magic member of staff, files an official complaint. In Defence Against the Dark Arts, Professor Lupin instructs the class in the defeat of a Boggart, which changes its form to appear as one's greatest fear. When Harry steps up, it manifests itself as a Dementor, however Lupin steps in to defeat it before Harry gets the chance.

Harry is told he can't go on the school outings to Hogsmeade, a local village inhabited solely by magical beings, as he hasn't got his admission slip signed, and watches his friends go without him. Instead, he meets with Lupin, and Harry discovers that the reason he wasn't allowed to fight the Boggart was that Lupin had been worried it would take the shape of Voldemort. This concern catches Harry by surprise, because Harry had been thinking even more fearfully about the Dementors. Later that night, Sirius Black breaks into Hogwarts and destroys the Fat Lady's (Dawn French) portrait that guards Gryffindor Tower. The students spend the night sleeping in the Great Hall while the teachers search the castle for Black. Because Black is believed at large in the castle Dementors are sent specifically to patrol the perimeter of Hogwarts. Next day, Professor Snape (Alan Rickman) replaces Lupin as Defence Against the Dark Arts teacher while Lupin is intriguingly "...incapable of teaching at the present time." In an odd divergence from routine, he teaches the class about Werewolves.

During the next school Quidditch match, a popular wizard sport, several Dementors approach and try to engage their powers over Harry, causing him to faint and fall off his broomstick. Dumbledore (Michael Gabon) breaks Harry's fall, but his broomstick flies off into the magical tree, the 'Whomping Willow' and is destroyed. Dumbledore is angry that the Dementors came within school grounds as they are prohibited from doing so. Harry wonders why the Dementors seem to have a special interest in him and Lupin reveals that this is due to the horrors within Harry's past. Harry considers that he needs to know how to defend himself against them and convinces Lupin as such, who agrees to teach him.

At the time of the next school outing, still keen to go to Hogsmeade, Harry attempts to sneak into the village under his Invisibility Cloak, but is caught by Fred and George Weasley (James and Oliver Phelps), who give him the Marauder's Map. It is a map of the entire school and shows the real-time locations of everyone on the grounds. Fred and George also tell Harry that the map shows the whereabouts of several secret passages out of Hogwarts, ideal for leaving undetected. Once in Hogsmeade village, and back under his Invisibility Cloak, Harry catches sight of the Minister Fudge and Professor Minerva McGonagall (Maggie Smith) chatting in the street, discussing Black and himself. He follows them as they go inside and is shocked to overhear that Sirius Black was his parents' best friend and is still his godfather and a legal guardian. Black supposedly divulged the Potter's secret whereabouts to Lord Voldemort and murdered their friend Peter Pettigrew, as well as twelve Muggle bystanders (non-magic humans). Harry vows to kill Black. On returning from the outing we find out from Hagrid that as a consequence of Lucuis Malfoy's complaint, Buckbeak has been sentenced to death. That same night, after hours, Harry is astonished when he sees the aforementioned Peter Pettigrew's name on the Marauder's Map. He goes looking for him but can't find him. After Professor Snape discoveres Harry out of bed, the map is confiscated by Lupin who meets them, and, covering for Harry, tells Snape it is merely a joke parchment and of no significance.

Harry has the agreed private class with Lupin, in which he must generate a Patronus, a shield that is used to repel the Dementors. Lupin has him test himself out on a Boggart. He fails the first time, but conjures one on his second attempt. Later on, returning to a recently finished Divinations class to bring back a crystal ball knocked over by Hermione, Harry reencounters Professor Trelawney. She grabs Harry by the shoulder, speaks as though possessed, and predicts that "...the Dark Lord's servant will return to him that night and that innocent blood shall be spilled."

When Harry, Ron and Hermione learn that Buckbeak is to be executed, they visit Hagrid in his hut to console him. On the way Draco taunts them about it and Hermione punches him in the face. While there, Hagrid says they cannot remain with him during the execution and that Buckbeak can't be set free, since the officials would know it was Hagrid. Hagrid has also found Ron's lost rat Scabbers, and returns him to Ron. Ron had wrongly believed that his rat had been eaten by Hermione's cat. As the execution party approaches the hut, stones fly in through the window and they leave and run back to the edge of the castle, watching the execution from afar. Scabbers then bites Ron, who chases after him, finally collecting him under the Whomping Willow. The black dog makes another appearance and attacks Ron and drags him, along with Scabbers, into a hole at the tree's base. Harry and Hermione follow, finding a tunnel which leads them to the Shrieking Shack.

Inside, in a fast moving scene, Harry finally confronts Sirius Black who he has been led to believe wishes to kill him, and whom he wishes to kill. We discover that as an illegal Animagus, Black can transform into any animal at will, thus he is also the infamous black dog. Professor Lupin, who had spotted the group on the confiscated Marauder's Map, suddenly bursts in and embraces his old friend Black. Confronted by Hermione, Lupin admits to being a werewolf. Lupin and Black then explain that Black is not the one who betrayed the Potters, rather it was Peter Pettigrew (Timothy Spall), who has been hiding for twelve years in his Animagus form as Scabbers, Ron's rat. H e is Voldemort's servant, not Black, and he framed Black for his crimes. Meanwhile Snape bursts in also confronting Black but is disposed of by Harry. Harry is skeptical of the story until Black and Lupin force Pettigrew back into his human form, and after some squealing resistance Pettigrew finally confesses that it is true, proving Black's innocence. Black further clears up the misunderstanding by explaining, that on discovering Pettigrew was still alive, he escaped Azkaban in order to kill him. As Lupin and Black are about to kill Pettigrew, Harry stops them, and showing Pettigrew mercy, tells him they will take him back to the castle, where he can be left for the Dementors.

As the group heads back to the castle, Harry and Sirius pause and chat optimistically. Harry remarks that Pettigrew would be have been of no use dead. Firstly he didn't want his father's two best friends to be killers, and secondly he is the key in proving Sirius' innocence. Sirius suggests Harry comes to live with him. They are disturbed however, when, as the full moon rises, it causes Lupin to turn into the dangerous werewolf since he had neglected to take his potion which inhibits this transformation. Black responds by transforming again into the black dog in order to protect Harry, Ron and Hermione. The werewolf and Black have a vicious fight. During the ensuing commotion, Pettigrew transforms himself back into the rat and escapes, not pursued. Harry runs forward in his angst at Sirius' torture at the hands of the werewolf, inadvertently attracting its attention. However while approaching Harry, it is distracted by some other distant werewolf cry. Meanwhile, Sirius, badly injured, has moved down to the nearby lake where he lies at the edge. Harry follows and kneels over him. As he does so, a swarm of Dementors approaches them. Harry produces a Patronus to try and fend them off, however it is not nearly strong enough and they both begin to submit to the Dementors. Then on the other side of the river appears the brilliant white symbol of a stag and an immense Patronus which drives the Dementors away. Harry faints.

Harry awakens in the hospital wing to hear the news, that Sirius Black has been captured and is about to be given the Dementor's Kiss, to suck out his soul. Dumbledore enters and Harry, Ron and Hermione try and convince him of Blacks' innocence. Dumbledore somehow already knows, but says that their word alone won't be believed. However, he suggests mysteriously, that Harry and Hermione travel in time back by using Hermione's time-turning device (we now find out how she has been attending simultaneous classes), and at least save both Black and Buckbeak from their fates. Hermione turns her hour-glass necklace back three turns (three hours), and Harry and Hermione are together thrust into the past, where they observe and remould the evenings events. They throw stones through the window of Hagrid's hut, alerting themselves of the approaching execution party. They rescue Buckbeak while the execution party is inside with Hagrid shortly before the execution, thus absolving Hagrid of any blame. Hermione diverts the attention of the werewolf Lupin stalking the past Harry with an imitation of another werewolf's cry. And, from a hiding place in the forest, Harry watches the Dementor sequence and realizes, as the stag symbol fails to appear, that he must have been the one who conjured the powerful Patronus. After saving his past self and Black from the Dementors, Harry and Hermione fly on Buckbeak's back to the tower, where Black is imprisoned, and rescue him. Harry and Black share a moment of contemplation, as since Black is going to be back on the run, still wanted and without proof of his innocence, their relationship will now be sadly fraught with complications and Harry's dream of living with his godfather is shattered. However, Harry takes comfort in knowing that Black, although still considered a fugitive, is at least free and safe for the time being. Black and Buckbeak leave, Black riding on his back. Harry and Hermione make it back to the hospital wing just as the timeline restores itself, and a reticent Dumbledore merrily bids them goodnight.

As the school year end approaches, Lupin announces that he is resigning, believing that parents of the students would not be comfortable in the now open knowledge that he is a werewolf. He returns the Marauder's Map to Harry since he is no longer a professor. Harry later receives a gift from an unknown source, a Firebolt, an extremely fast racing broom. Hermione holds up a large feather, also contained within the parcel, confirming that Sirius must have sent it. Harry tries it out and is whisked away from sight, ending the film with the snapshot image of Harry flying his new broom, ecstatic.

Harry Potter and the Chamber of Secrets

While home with the Dursleys for the summer, Harry Potter (Daniel Radcliffe) is not getting any mail from his friends, Ron (Rupert Grint) and Hermione (Emma Watson). On his twelfth birthday (July 31) Harry is visited by Dobby, a house-elf, who warns Harry that he will be in mortal danger if he returns to Hogwarts. Harry ignores Dobby's warning and is determined to return. It turns out that Dobby has been collecting Harry's letters to make it seem as though his friends had forgotten him, hoping Harry might then not want to return to Hogwarts. Seeing that he will have to use force, Dobby decides to destroy, by the use of a charm, a large cake that Aunt Petunia (Fiona Shaw) has baked for an important dinner party attended by Vernon Dursley's (Richard Griffiths) boss and his wife. Harry is blamed by the Ministry of Magic for Dobby's charm, and is told that if he does magic outside school again, he will be expelled. On learning that Harry cannot perform magic outside school, the Dursleys, previously fearful of his wizarding, lock Harrys books and wand away and Vernon Dursley fits bars onto his bedroom window, making Harry a prisoner.

A few days later, Fred, George (James and Oliver Phelps) and Ron Weasley come to his rescue in their father's enchanted Ford Anglia. After a pleasant summer together in the the Weasley house, everyone heads 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. In desperation, they fly to Hogwarts in the car, crashing into the Whomping Willow and damaging Ron's wand. The semi-sentient car ejects them and their belongings and disappears into the Forbidden Forest.

Harry soon finds he is the unwanted centre of attention of three people: the vain new Defense Against the Dark Arts Professor, Gilderoy Lockhart (Kenneth Branagh), admirer Colin Creevey (Hugh Mitchell), and Ron's sister, Ginny Weasley (Bonnie Wright), who fancies Harry. Events take a turn for the worse when the Chamber of Secrets is opened and a monster stalks the castle, with the power literally to petrify several students. According to legend, the Chamber was built by Salazar Slytherin and can only be opened by his heir, in order to purge Hogwarts of students who are not pure-blood wizards. Many suspect Harry is the Heir of Slytherin, especially after he inadvertently speaks Parseltongue (the language of snakes), a rare ability Harry gained after Voldemort's murderous attack upon him when he was an infant.

Harry, Ron, and Hermione attempt to discover the Heir of Slytherin's true identity. Using Polyjuice Potion brewed by Hermione, they disguise themselves as Slytherin students, Crabbe (Jamie Waylett) and Goyle (Josh Herman), hoping to learn from Draco Malfoy (Tom Felton) the identity of the Heir. Malfoy, they learn, does not know who the Heir of Slytherin is, but he inadvertently provides Harry and Ron with an important clue about the Chamber of Secrets.

Unfortunately, the hair that Hermione took from Millicent Bullstrode's uniform was from a cat, and as the polyjuice potion is only intended for human transformations she assumes a feline appearance; it takes a little more than a month to restore her normal human form. She is released from the hospital wing in early February, her normal appearance restored.

The attacks increase throughout the year, petrifying more students, including Hermione. Most horribly, a message written on a wall declares that Ginny Weasley has been taken into the Chamber, where "her skeleton will lie forever."

With the help of Ron and Moaning Myrtle (Shirley Henderson), Harry discovers the entrance to the Chamber of Secrets. They force Gilderoy Lockhart, a fraud who wipes clean other wizards' memories and claims their achievements, to go with them. Once they find the entrance to the Chamber, Lockhart attempts to use Ron's broken wand to erase Harry and Ron's memories, but the spell backfires on to himself and brings the ceiling caving in, separating Harry from Ron and Lockhart. Lockhart revives, but has now lost his own memory.

Harry makes it to the Chamber where he finds an unconscious Ginny. He also meets a young man named Tom Riddle, who claims to be a "memory". Harry learns that Ginny, under the control of Lord Voldemort, opened the Chamber. Voldemort, whose real name is Tom Marvolo Riddle (the anagram of which is "I am Lord Voldemort"), imprinted his memory in an enchanted diary, in order to one day continue the work he began when he reopened the Chamber fifty years ago ridding Hogwarts of non-pureblood witches and wizards. It was Hagrid, a Hogwarts student at the time, who was blamed for the attacks and expelled.

Tom Riddle's memory grows more powerful as it steals life from Ginny's body, and it tries to kill Harry by setting loose a basilisk (the monster responsible for petrifying the students). But Dumbledore's (Richard Harris) phoenix, Fawkes, arrives carrying the Sorting Hat, from which Harry draws out the sword of Godric Gryffindor. Fawkes blinds the basilisk, destroying its fatal gaze, and Harry slays it with the sword. In attempting to slay the basilisk Harry's arm has been pierced by the creature's fang. Harry stabs the diary with one of the basilisk's fangs, and the memory of Riddle is destroyed, while Ginny revives from her near-death state. Harry seems to be dying quickly from the venom but Fawkes comes to heal Harry with his tears (phoenix tears have healing power). Ginny and Harry both recover fully, along with those who were petrified: Hermione, Mrs Norris, Justin Finch-Fletchley, Nearly Headless Nick (John Cleese), and Colin Creevey.

Harry realizes it was Lucius Malfoy (Jason Isaacs), Draco Malfoy's father, who slipped the diary into Ginny's cauldron when he encountered the Weasleys in a Diagon Alley bookshop, but he is unable to prove it. Dobby reveals he is the Malfoys' servant, and knowing their treachery, had been trying to protect Harry all year. In gratitude, Harry sticks one of his old socks into the diary and hands it to Lucius. Lucius throws away the diary, but Dobby catches it and finds the sock hidden in its pages. This constitutes, in Dobby's eyes, a gift of clothing the traditional manner in which a master frees a house-elf from servitude. The freed Dobby declares he is eternally grateful to Harry and protects him from an attempted reprisal from Lucius. The word "Avada" is used as the beginning of Lucius Malfoy's curse, suggesting that it is the Avada Kedavra (the killing curse).

Dumbledore dispels Harry's fears that he could have been put into Slytherin rather than into Gryffindor when he tells Harry that it is his choices that define him and not his abilities, and that Harry could not have wielded the sword of Gryffindor if he did not truly belong

Harry Potter and the Sorcerer's Stone

Lord Voldemort, an evil and powerful dark wizard, has just been defeated. When he tried to kill a one-year-old boy, Harry Potter (Daniel Radcliffe), the killing curse rebounded upon him, destroying his body. Harry is left an orphan with a lightning-bolt scar on his forehead, Voldemort having killed his parents, Lily (Geraldine Somerville) and James (Adrian Rawlins) Potter. Professors Dumbledore (Richard Harris) and McGonagall (Dame Maggie Smith) and Gamekeeper Hagrid (Robbie Coltrane) leave him on the doorstep of his ultra-conventional, insensitive, negligent Muggle (non-magical) relatives, the Dursley family, who take him in. Harry's relatives decide to conceal his magical heritage from him and make him live in a cupboard under the stairs for ten years.

Shortly before Harry's eleventh birthday, he receives a letter addressed specifically to him. His outraged uncle, however, reads and burns it before Harry has a chance to look at the contents. The sender does not give up, and the Dursleys receive successively larger numbers of the same correspondence. Soon, his Uncle Vernon (Richard Griffiths) becomes so paranoid that the Dursleys, with Harry in tow, hide in a hut on a small island to escape. That night (which happens to be before Harry's birthday), he is visited by an enormous man named Hagrid who bursts through the locked door of the hut. With Hagrid holding the Dursleys at bay, Harry finally reads his letter, in which he learns he has been invited to study magic at Hogwarts School of Witchcraft and Wizardry. The next day Harry and Hagrid head to Diagon Alley in London (the secret magical location hidden behind the famous wizarding pub The Leaky Cauldron). Harry enters the wizarding world for the first time, learns to his surprise that he is famous, and meets the new Hogwarts Defense Against the Dark Arts teacher, Professor Quirrell (Ian Hart). He takes the train to Hogwarts from Platform Nine and three-quarters, befriending Ron Weasley (Rupert Grint), and meeting Hermione Granger (Emma Watson), a Muggle-born witch.

Upon arrival, the Sorting Hat places Harry, Ron and Hermione in Gryffindor House. Draco Malfoy (Tom Felton), an arrogant and elitist student, gets placed in Slytherin. At the end of their first week at Hogwarts, Harry and Ron discover that Gringotts, the wizarding bank, was broken into and a vault that Harry and Hagrid visited had been the subject of the robbery. Later, Harry discovers he has a talent for riding broomsticks, and after an incident with Malfoy, is recruited to join Gryffindor's Quidditch team as a Seeker, much to Malfoy's displeasure.

Harry, Ron, Hermione explore Hogwarts late at night and accidentally stumble across the door to a corridor. A three-headed dog, christened Fluffy by Hagrid, guards a trapdoor. On Halloween, Quirrell informs everyone that a troll has entered the castle; Harry and Ron fight the troll to save Hermione, who is trapped in the girls' bathroom, and the three become best friends.

At Harry's first Quidditch match, Harry's broom becomes possessed, nearly knocking him off. Hermione sees Professor Severus Snape (Alan Rickman), the sinister Potions master and head of Slytherin House, staring at Harry and mouthing words, making her believe that Snape has caused the broom to misbehave with a dark curse. Hoping to save Harry, Hermione sets Snape's robes on fire, distracting him and others and allowing Harry to survive.

At Christmas, Harry receives an Invisibility Cloak, once belonging to his father, which renders its wearer invisible. Harry uses it to explore the Restricted Section in the library to research information on Nicolas Flamel, a name Hagrid lets slip when confronted about his knowledge of Fluffy. Eventually, Harry learns that "Nicolas Flamel is the only known maker of the Sorcerer's Stone, which produces the Elixir of Life which will make the drinker immortal."

Harry sees Snape trying to get information from Quirrell about getting past Fluffy; Quirrell says he does not know what he's talking about. Harry, Ron, and Hermione are sure that Snape is trying to steal the Philosopher's Stone in order to restore Lord Voldemort to power, but Hagrid denies it. While at Hagrid's hut, the trio discover a dragon egg Hagrid was nursing in a fire. Later the egg hatches a Norwegian Ridgeback dragon, and Hagrid decides to call him "Norbert". The friends are nervous for Hagrid, since dragon breeding had long been outlawed in the wizarding world, and Hagrid had something of a reckless nature, who has long since nursed a strong desire for a dragon. Finally, Harry, Ron, and Hermione are able to convince Hagrid to let Norbert go live with other dragons of his kind in Romania.

Harry, Hermione, Ron and Draco are caught out late at night, and are forced to serve detention with Hagrid in the Forbidden Forest. Harry sees a hooded figure drink the blood of an injured unicorn, which makes Harry's forehead scar start burning. Firenze, a centaur, tells Harry that it is a monstrous thing to slay a unicorn, let alone drink its blood. He also tells Harry that unicorn blood will keep one alive, and that the hooded figure is in fact Voldemort.

Harry, Hermione and Ron find out that Hagrid has told a hooded stranger how to get past Fluffy, and they believe the theft of the Stone is imminent. Rushing to finally confide in Professor Dumbledore their news, they meet Professor McGonagall, who is shocked to find out how much they knew about the Stone, but reassures them all the same that it is safe in the castle. She also tells them that Dumbledore has been sent away on an important mission by the Ministry of Magic. Positive that Dumbledore's summons was a red herring to take Professor Dumbledore away from Hogwarts, the trio make plans to thwart Snape's theft of the stone. They set out to reach the stone first, navigating the security system set up by the school's staff, which is a series of complex magical challenges. The three make it through together until finally, Harry must enter the inner chamber alone. There he finds that Professor Quirrell, not Snape, is attempting to steal the Stone. Realizing that Snape was trying to protect him from harm all along, Harry confronts Quirrell and survives a second encounter with Lord Voldemort, who has possessed Quirrell and appears as a ghastly face on the back of Quirrell's head. Quirrell crumbles when he touches Harry's skin, and Harry passes out because of his close proximity to Lord Voldemort. Voldemort then pitilessly abandons Quirrell, who dies in the aftermath of his possession.

Harry wakes up in the hospital wing. Dumbledore reveals to Harry that Harry's mother died to protect Harry as an infant. Her pure, loving sacrifice provides Harry with an ancient magical protection from Voldemort's lethal spells and also prevents Voldemort from touching Harry without suffering terribly. Dumbledore also says that the Sorcerer's Stone has been destroyed to prevent future attempts by Voldemort to steal it.

Finally, at the end-of-year feast, the House Points totals are given: Gryffindor is in last place. However, Dumbledore gives a few "last-minute additions", granting points to Harry, Ron, and Hermione, so that Gryffindor wins the House Cup.
