The only remaining flying city, Laputa, still floats in the sky, concealed by a permanent powerful hurricane that surrounds it.In the story's opening, an airship carrying Sheeta, a girl who has been abducted by Muska, a secret agent working for the government, is attacked by Captain Dola and her air pirate sons who are in search of Sheeta's crystal amulet. In the resulting struggle, Sheeta falls from the airship but her descent is slowed by the amulet which starts glowing. She safely lands in a small mining town where she is discovered by a boy named Pazu, who takes her into his home to recover. On waking, Sheeta is surprised to find that Pazu is building a small aeroplane with the intention of finding the lost city of Laputa, which his father had taken a photograph of while flying some years previously. She tells him that her family lived in a small valley to the north named Gondoa, and that she lived alone once her mother, father, and grandmother died, until Muska and his agents abducted her. Later that day they are pursued by Dola's pirates, and then by Muska's soldiers. Eventually, the two fall into an abandoned mine, where they encounter the local eccentric 'Uncle Pomme', who informs them that Sheeta's amulet is made of 'volucite' crystal ('Aetherium' in the American release), a material used to keep Laputa and the other flying cities aloft.[2]Upon leaving the mines, Sheeta tells Pazu that her full name is 'Lusheeta Toel Ul Laputa'. They are then captured by Muska and taken to the fortress of Tedis, where Pazu is imprisoned in the fortress' dark, cold and damp tower while Sheeta is imprisoned in a more lavish room....
