Harry Potter and the Sorcerer's Stone

The Dursleys' world of aggressive normality is disrupted when baby Harry is left on their doorstep. Ten years later, Harry lives in a cupboard, bullied by his cousin Dudley, until strange events — a vanishing glass at the zoo, a boa constrictor set free — signal that something about Harry cannot be contained.

Hogwarts letters flood Privet Drive in increasing absurdity — through the mail slot, down the chimney, inside eggs — until the Dursleys flee to a shack on a rock in the sea. On Harry's eleventh birthday, Hagrid breaks down the door and tells Harry the truth: he is a wizard, his parents were murdered by Voldemort, and he is famous.

Hagrid takes Harry shopping in Diagon Alley — wand, robes, owl, and a Gringotts vault full of gold. Hagrid secretly retrieves a small package from vault 713. Harry boards the Hogwarts Express at Platform Nine and Three-Quarters, meets Ron Weasley and Hermione Granger, and first encounters Draco Malfoy's pure-blood snobbery.

Harry is Sorted into Gryffindor after silently begging the Sorting Hat not to put him in Slytherin. He navigates classes, clashes with Snape, discovers his natural talent for flying, and is recruited as Gryffindor's Seeker — the youngest in a century.

Harry and Ron rescue Hermione from a mountain troll on Halloween, forging the trio's bond. They discover Fluffy the three-headed dog guarding a trapdoor. Harry plays his first Quidditch match while someone jinxes his broom. At Christmas, Harry receives his father's Invisibility Cloak and discovers the Mirror of Erised.

The trio finally identifies Nicolas Flamel as the creator of the Philosopher's Stone and deduces that the Stone is what Fluffy is guarding. Hagrid hatches an illegal dragon egg, creating a crisis that results in Harry and Hermione losing 150 house points and getting detention in the Forbidden Forest.

Convinced that Snape will steal the Stone, Harry, Ron, and Hermione bypass Fluffy and descend through the trapdoor, facing a series of enchanted obstacles: Devil's Snare, flying keys, a giant chess game, and a logic puzzle. Ron sacrifices himself on the chessboard; Hermione solves the potions riddle; Harry goes on alone.

Harry confronts not Snape but Quirrell, who reveals that Voldemort has been living on the back of his head. Harry retrieves the Stone from the Mirror of Erised because he wants to find it but not use it. Quirrell's skin burns when he touches Harry — Lily's sacrificial love protects her son. Dumbledore arrives, the Stone is destroyed, and Dumbledore explains everything.

Dumbledore awards last-minute points to Harry, Ron, Hermione, and Neville, giving Gryffindor the House Cup. Harry returns to the Dursleys for the summer, but everything has changed — he has a home, friends, and knowledge of who he is.
