The story is about a boy, Harry an orphan that he lived with his aunt
and his uncle and their son Dudley.
When they go to the zoo for Dudley's birthday, Harry encounters a
sympathetic snake. He's able to speak to the friendly reptile and somehow seems
to have removed the glass from its cage, so it can go back to Brazil. After the
trip to the zoo, mysterious letters start arriving for Harry. His uncle, Mr.
Dursley, is furious and tries to keep them from Harry. But the letters keep
arriving at such a rapid rate that, the evening before Harry's eleventh
birthday, his uncle takes the whole family to a deserted island to escape all
of the mail.
They can't hide for long, though; Hagrid shows up on Harry's
birthday to deliver the letter, and the news that Harry's a wizard and has been
admitted to the Hogwarts School of Witchcraft and Wizardry. The next day he takes
Harry to shop for school supplies at Diagon Alley, where Harry learns more
about the wizarding world. He meets Malfoy and Hogwarts' new Defense against
the Dark Arts professor, Quirrell. Harry also buys his first wand. Hagrid also
picks up a mysterious package at Gringotts, the goblin bank.
Later that summer, Harry travels to Hogwarts. He has to take a train
from platform nine and three-quarters, a magical platform! A family called the
Weasleys helps him find his way, and he begins to make friends with one of
their sons, Ron. He meets other first-year students like Hermione Granger and
Neville Longbottom.
Upon their arrival at Hogwarts, the first years are sorted into one
of four houses. Harry, Ron, Hermione, and Neville are all Gryffindors; Malfoy
is a Slytherin. They begin taking all kinds of classes in magic. Harry dislikes
the Potions teacher, Snape, who is unfair and kind of mean.
Harry learns that there was an attempted robbery at Gringotts bank,
but nothing was taken. He guesses that the robbers were after what Hagrid
picked up. Hagrid lets it slip that it has something to do with someone called
Nicolas Flamel.
Malfoy becomes a big bully. During their first broom-flying lesson,
he teases Neville. In defending Neville, Harry realizes he's a natural at
flying. He's a superstar on a broomstick. Although Harry's broken rules by
flying unsupervised, Professor McGonagall rewards him by putting him on the
Gryffindor Quidditch team as Seeker
Later, Malfoy and Harry have a fight, and Malfoy challenges Harry to
a wizard duel at midnight. Hermione and Ron accompany Harry, but Malfoy doesn't
show – he was trying to get them in trouble for roaming the school while they
should be in bed. As they hurry to get back to the dorm, the three friends
stumble into a forbidden part of Hogwarts, where they bump into a three-headed
monster dog. Luckily, they escape in the nick of time.
Harry and Ron aren't getting along with Hermione, but make up when
they rescue her from a troll that's terrorizing the school. Though they get in
trouble to taking on the troll alone, they also show their bravery. Now the
three are inseparable.
As the first Quidditch match approaches, the three friends suspect
Snape of wanting the package from Gringotts. During the game, Harry's broom
acts weird and seems to be hexed. Harry's saved, but his friends blame Snape
for putting him in danger.
During the winter break, Harry stays at Hogwarts and is given an
invisibility cloak that once belonged to his dad. He uses it to sneak around
the castle and discovers the Mirror of Erised in one of Hogwarts' many secret
rooms. When he looks into the mirror he sees his parents, but when he shares
the mirror with Ron, Ron sees himself as a hero. Dumbledore catches Harry at
the mirror and explains that the mirror shows you your heart's desire. The wise
old wizard then says he's going to take the mirror away because it's dangerous.
When classes resume after winter break, Harry, Ron, and Hermione
figure out woh Flamel is an alchemist and the only person in the world to have
the Sorcerer's Stone, which can provide immortality. They decide the Stone must
be what was hidden at Gringotts and is now being guarded by the three-headed
dog.
When not trying to solve the mystery of Nicholas Flamel, Harry is
trying to balance Quidditch and school work. Gryffindor wins another Quidditch
game, which Snape referees, and then Harry hears Snape and Quirrell arguing.
Meanwhile, Hagrid adopts a dragon, which is illegal. Ron, Hermione,
and Harry have to convince him that's it's just not practical to raise a baby
dragon, and find a way to smuggle the dragon out. Malfoy spies on them and
tries to turn them in. When Harry and Hermione have successfully sent the
dragon out in the middle of the night, they're caught by McGonagall along with
Neville, who was trying to warn them, and Malfoy, who tattled and are given
really big detention. Gryffindor moves to the last place in the house cup
contest, and everyone is really mad at them.
Harry, Hermione, Neville, and Malfoy have detention with Hagrid in
the forest at night. They are supposed to figure out what's killing unicorns
and drinking their blood. Harry runs into some centaurs that see trouble ahead
in the stars. They all realize that Voldemort is trying to return and that he's
the one killing unicorns.
After the first-year exams, Harry, Ron, and Hermione talk with
Hagrid and realize that he said too much about the Sorcerer's Stone to the
mysterious stranger who gave him the dragon. Harry, Ron, and Hermione suspect
that Snape is after it. That night they try to retrieve the Stone. Neville
attempts to stop them, so they have to temporarily paralyze him with magic.
They pass by the three-headed dog by playing it music, only to meet with
another series of challenges. First, they're trapped by a Devil's Snare plant,
then they have to catch a flying key, and then they have to play a life-size
game of wizard chess. The chess game takes Ron out, leaving Harry and Hermione
to solve a logic puzzle and drink potions to go forward. There's only enough
for one, so Harry moves on and sends Hermione back for help.
To Harry's surprise, he runs into Quirrell, not Snape like he
thought he would. Quirrell reveals that Voldemort is living in him like a
parasite. He tries to use Harry to get the Stone. He makes Harry use the Mirror
of Erised, and Harry finds himself holding the Stone and lying about it.
Quirrell/Voldemort tries to kill Harry, but when he touches Harry, he burns. Harry
blacks out when Harry comes to, he's in the infirmary with Dumbledore, and
Quirrell is dead. Dumbledore explains that Harry defeated Quirrell/Voldemort
through the protection of his mother's love. He also mentions that the Stone
has been destroyed.
Later, at the end-of-year banquet, Dumbledore praises Ron, Hermione,
Harry, and Neville for the parts they played in defeating Quirrell. He rewards
them by giving Gryffindor house tons of points. They win the
house cup for Gryffindor, and even pass all of their exams. Then, they leave
Hogwarts for the summer and part ways at the train station. Though it stinks to
be returning to the Dursleys, Harry explains how much easier his time with them
will be now that he can do magic.
