This high-flying adventure begins when Pazu, an engineer’s apprentice, spies a young girl, Sheeta, floating down from the sky, held aloft by a glowing pendant. Both Sheeta and Pazu are searching for the legendary floating castle, Laputa, and they vow to travel there together to unravel the mystery of the luminous crystal. But their quest won’t be easy, as soon they are being pursued by greedy air pirates, the military, and secret government agents, who all seek the power Sheeta alone can control.
