Percy Jackson & the Olympians: The Lightning Thief

On top of the Empire State Building, Olympian gods Zeus and Poseidon meet, where Zeus reveals that his master lightning bolt has been stolen and accuses Poseidon's demigod son Percy Jackson of the theft. Poseidon reminds him that Percy is unaware of his true identity, but Zeus declares that unless Percy returns the lightning bolt to Mount Olympus before the next summer solstice, war will be waged. Percy is a seventeen-year-old teenager who appears to be dyslexic, but has a unique ability to stay underwater for a lengthy time. While on a school trip to the local museum, Percy is attacked by a Fury disguised as his substitute teacher, who demands the lightning bolt. Percy's best friend Grover Underwood and Latin teacher Mr. Brunner, both of whom appear disabled, help Percy and scare off the Fury. Upon learning the Fury's reason for the attack, Mr. Brunner gives Percy a pen and tells him it is a powerful weapon and has Grover take Percy and his mother Sally out to Camp Half-Blood, leaving behind Sally's lazy husband Gabe Ugliano. However, the three are attacked by a minotaur who appears to kill Sally, since she is unable to enter the camp. Grover tells Percy to use the pen, and Percy discovers that it is actually a sword, which he uses to fight the minotaur, without initial success. Percy kills the minotaur with its own horn and then faints from shock. Three days later, Percy wakes up in the camp. He learns that he is the son of Poseidon, Grover is really a satyr and his protector, and Mr. Brunner is really the centaur Chiron. Chiron suggests Percy go to Mount Olympus and convince Zeus of his innocence. Percy begins his training to use his demigod powers (which include water manipulation and using water to heal), and meets other demigods including Annabeth Chase, daughter of Athena, and Luke Castellan, son of Hermes. After assisting in a team exercise, Percy is visited by a fiery apparition of his uncle Hades, who reveals that Sally is with him in the Underworld and he will return her safely if Percy hands over the lightning bolt. Defying Chiron's orders, Percy goes to the Underworld, joined by Grover and Annabeth. They visit Luke, who gives them a map showing three of Persephone's pearls that they can utilize to escape the Underworld, an old shield, and a pair of winged sneakers Luke stole from his father. The trio head out, locating the first pearl at an old garden center but encountering Medusa, who tries to kill them until decapitated by Percy - her head taken with them for further use. They locate the second pearl in the Parthenon in Nashville, and Percy uses the winged shoes to take it from a statue of Athena. Afterwards however, they are confronted by Hydra, whom Grover petrifies using Medusa's head. The third pearl is located in Las Vegas in the Lotus Casino, where the three eat lotus flowers and forget their reason for being there. They wind up in the casino for five days until Percy's dad Poseidon speaks into Percy's mind, helping Percy come to his senses, and Percy then goes and helps Grover and Annabeth do the same and they flee, discovering the casino is run by the Lotus-Eaters. With all three pearls in their possession, Percy, Grover and Annabeth head into the Underworld, the portal for which is located in Hollywood.
