Ordinary World: Harry is an ordinary 11 year old boy, orphaned, living with his only living relatives.
Call: Harry begins recieving letters. Letters sent directly to him 'To Mr. Harry Potter, Number Four Privet Drive, Surrey; The Cupboard Under the Stairs'. His Aunt Petunia and Uncle Vernon know who they're from, but don't want him to know. Another Call could be when Rubeus Hagrid, the groundkeeper at Hogwarts, School of Witchcraft and Wizardry, comes to collect Harry from his relatives and bring him to the school that's chosen him, telling him that Harry is a wizard. Hagrid says, 'A ruddy good one at that, I'd wager', which leads to a bigger concluson and question about who he is.
Refusal: When Hagrid tells Harry what he is and how his parents really died, Harry tells him it's impossible. 'I c-can't be a w-wizard. I'm - just Harry. Just Harry.'
Mentor: Hagrid goes on to tell him 'Have you ever made anything happ'n? Anythin' you couldn' explain when you were angry, or - or scared?' He reassures him that's how all great witches and wizards start out.
Threshold: When Harry and Hagrid journey to Diagon Alley, he begins to believe and wonder about who he is, how is parents died and why he became so famous when he didn't know he was. He then hears about people calling him the 'Boy Who Lived'.
Tests, Allies, Enemies: Hagrid ends up telling Harry about Lord Voldemort, the most powerful, Dark Lord ever to live in the wizarding world. He tells him how his parents died, how Harry recieved the lightning bolt scar on his forehead from Voldemort and how he was destroyed. But, rumor has it that he didn't just die. That he is still alive. But only just. He meets his soon-to-be best friends, Ronald Weasley and Hermione Granger, two friends who we would never expect him to gain and keep in his next adventures. He also meets Draco Malfoy, a pureblood whose father is well-known to be rich and powerful. He all but orders Harry to be his friend 'You don't want to get involved with the wrong sort. I can help you there'. He meets Professor Dumbledore, the Headmaster of Hogwarts, his future mentor and best teacher and tutor. Professor Snape, whom Harry already begins to hate with a burning passion, emerges, along with Professor Quirrell, a stammering, confused, worrisome man who teaches DADA (Defense Against the Dark Arts).
Approach: They arrive at Hogwarts on the Hogwarts Express from Platform Nine and Three-Quarters. The first years, Harry, Ron, Hermione, Neville and the rest are sorted into Houses (Slytherin, Hufflepuff, Ravenclaw and Gryffindor), have their beginning of Term feast in the Great Hall and begin with their first classes, learning spells and potions.
Ordeal: Harry, Ron and Hermione together find their way to discover that the Philosopher's Stone - a stone of unimaginable power, the ability to keep you alive for the rest of eternity - is going to be stolen by Professor Snape, who turns out to be Quirrell instead. The trio fights their way through a series of challenges and trials, including a giant, intense game of Wizard's Chess and a nasty infestation of Devil's Snare. Harry finds Quirrell, who turns out to be Voldemort in disguise.
Reward: They fight, Harry wins, barely making it out alive. He protects the Stone from Voldemort and destroys him (partially), sending him out of the school.
The Road Back: The students are on their ways back home on the Hogwarts Express.
Resurrection: Harry, Ron and Hermione all return from the Hospital Wing, recovered and well from their expedition and triumph against Voldemort.
Return with the Elixir: Going onto the train, Harry realizes where he belongs. 'I'm not going home. Not really'.
