Chihiro, a young girl, and her parents are moving into a different town. On the way they get lost and end up leaving the car at the entrance to a mysterious cave leading into an abandoned theme park. There, a strange spell cast upon Chihiro's parents will turn them into pigs and force her to go on a magical adventure into another world to save her parents and return them to their original form.
The two have a very similar atmosphere and the main characters in both films remind you of one another in many ways. In addition, there are plot similarities as the two pieces deal with a girl who moves to a new place with her parents against her will. She then encounters supernatural creatures, not too happy about it at first but later learns to befriend them.
