Log line: An energetic boy who was born in an isolated island after the destruction of the earth meets a girl, who is the granddaughter of a scientist, and saves her from a bad guy who tries to reach her grandfather to rule the world.
This is a boy’s “saving the heroine” adventure in a post apocalyptic world. People in a beautiful island are trying to live natural lives, but a bad guy in another island tries to rule the world. It’s the directorial debut of Hayao Miyazaki, and is one of my favorite anime of his.
The theatrical version is summarized from the TV series, and is too short to tell the story. I recommend watching TV series.
