What happens in Percy Jackson & the Olympians: The Lightning Thief?
Percy Jackson, a 12-year-old boy in New York City, begins his story struggling with dyslexia and ADHD, often getting expelled from schools. During a school field trip to the Metropolitan Museum of Art, his teacher Mrs. Dodds transforms into a Fury and attacks him. His best friend Grover Underwood reveals himself as a satyr, and Percy's Latin teacher Mr. Brunner gives him a magical pen that turns into a sword, Riptide. Percy returns home to his mother Sally Jackson; they flee to Camp Half-Blood but are attacked by the Minotaur. Sally is seemingly killed, and Percy defeats the Minotaur. At camp, he learns he is a demigod, son of Poseidon, and meets Annabeth Chase, daughter of Athena, and the camp director Dionysus and centaur Chiron (Mr. Brunner). Percy's father claims him with a trident symbol over the campfire.
Zeus's Master Bolt has been stolen, and Percy is accused. A prophecy says he must retrieve the bolt and return it to Olympus before the summer solstice, or war will break out. Percy, Annabeth, and Grover embark on a quest. They first encounter Medusa, who tries to turn them to stone; Percy decapitates her and sends her head to the gods. They are attacked by an Echidna and a Chimera; Percy falls into the Mississippi River and is healed by his father. They make their way to the Lotus Hotel and Casino in Las Vegas, where time stands still; they escape and reach the entrance to the Underworld in Los Angeles, guided by a naiad.
Inside the Underworld, they bargain with Hades, who believes Percy stole the Helm of Darkness. Hades reveals that Percy's mother Sally is trapped there. Using the pearl from the Lotus Hotel, they escape with Sally and retrieve the Master Bolt and Helm from their backpacks—actually planted there by Luke. Hades realizes he was tricked and accepts the Helm. Percy, Annabeth, Grover, and Sally return to the surface. Percy flies to Mount Olympus, gives the Master Bolt to Zeus, and reveals that Luke was the real thief. Percy confronts Luke at Camp Half-Blood; Luke admits he wants to overthrow the gods and has been working for Kronos. Luke tries to kill Percy with a scorpion, but Percy uses his water powers to defeat him. Luke escapes on winged sandals. The film ends with Percy, Annabeth, and Grover together, with Percy deciding to spend the summer at camp.
