Poor, poor Harry Potter. Orphaned as an infant, he's been raised by his beastly aunt and uncle who keep him locked in the room under the stairs and make him serve breakfast. But 11-year-old Harry (Daniel Radcliffe) has always known he was different, a fact confirmed in a big way when he's invited to enroll at the Hogwarts School of Witchcraft and Wizardry. Despite his horrid family's protests, Harry's whisked off by a giant named Hagrid (Robbie Coltrane) to the magic school, where it seems he's something of a celebrity. Turns out his parents were killed by a wicked "fallen wizard," who, despite his mighty powers, was somehow unable to kill the baby Harry. It will eventually fall to Harry to stop the malevolent sorcerer who still roams the countryside, plotting to get hold of a magic stone secreted inside Hogwarts that will give him absolute power. Meanwhile, Harry makes some new friends in bossy Hermione (Emma Watson) and affable Ron (Rupert Grint), becomes a star player of Quidditch (like hockey on broomsticks) and defeats a troll rampaging through the girls' bathroom.
