|aYoung Mia lives on an island that is currently being transformed into a lavish resort by an unscrupulous real estate developer. Her father Pedro is one of the laborers charged with constructing the resort, though lately the project has been beset by a series of mysterious problems. Those problems become rather serious when Pedro winds up buried in a tunnel after a massive landslide, and Mia races though the jungle to aid in the rescue mission. Along the way, Mia encounters the Migou, a race of curious, identical creatures that can take any form they please. The Migou protect a tree that is crucial to the future of all living creatures on Earth, and that tree is in danger due to the development that Mia's father has been working on.
