Originally, she came from Gondoa, deep in the northern mountains, and raised cattle alone, until the day Colonel Muska's men came and took her away. She was Muska's prisoner until Dola, a pirate captain, arrived and tried to steal her crystal. Sheeta fell out of an airship and came across Pazu, who rescued her. Pazu helps her escape from Dola and her crew and they discover the secret of Laputa's power. Sheeta tells Pazu she is descended from the people of Laputa. The two of them are captured by Muska and the army. Sheeta learns the secret and convinces Pazu to forget about Laputa for their own good. Remembering a spell from long ago, Sheeta recites it and the sacred light brings a huge robot back to life. It scares off the soldiers and hands her over to Pazu, who saves her again. Dola welcomes Sheeta and Pazu to her crew instead of holding them hostage and gives them work. After a battle in the clouds, the heroic twosome finally discover Laputa and, discovering the palace under attack and Dola and the boys held prisoner, realize they must rescue the city from Muska's evil plan. Sheeta notices Muska preparing to open a door leading to the royal chambers but is kidnapped. Pazu frees Dola and the boys and rushes to save Sheeta. Meanwhile, Muska seizes power over Laputa, but Sheeta breaks free and pulls the crystal out of his grasp. The evil man forces her to obey him, but Sheeta stands her ground and refuses, telling him that the kingdom died out because its leader was cruel and the world cannot live without love. Pazu steps up and faces Muska, who threatens to kill Sheeta if the two of them don't comply. Pazu convinces him that he'll do it if he lets him talk to Sheeta. Muska reluctantly agrees and gives them a minute. Sheeta and Pazu recite the spell of destruction, destroying the castle and causing Muska to fall to his death. The battle won, our heroes realize that the huge tree living in the middle of the kingdom has saved them with its roots. Then they sail off into the sky, with Dola and her crew alongside them.
- Sheeta is similar to Rogue from the X-Men film series:
- Both are portrayed by Anna Paquin.
- Both are targeted by the main villains for a special reason (Sheeta is targeted by Muska for crystal amulet, Rogue is targeted by Magneto for his machine to turn humans into mutants).
- Both are able to live a normal life in the end with a boy (Sheeta started a new life together with Pazu, Rogue took the mutant cure to love Iceman).
