Young orphan Sheeta and her kidnapper, Col. Muska, are flying to a
military prison when their plane is attacked by a gang of air pirates
led by the matronly Dola. Escaping from a mid-air collision via a magic
crystal around her neck, Sheeta meets fellow orphan Pazu and the pair
join forces to discover the mystical floating city of Laputa while pursued by both Muska and the pirates, who lust for the city's myriad treasures.
