Grade schooler Ryonosuke (Kamiki Ryonosuke) has just moved to a small town with his father (Miura Tomokazu), a government official overseeing the area's unpopular airport construction project. Ryonosuke finds a new friend in milk delivery boy Kohei (Sasano Yuma) who introduces him to all the local eccentrics including Hiharu (Ohgo Suzuka), a young girl who believes she can communicate with UFOs. Kohei's dad (Kohinata Fumiyo) is also pretty strange himself, a biologist who went off on an endangered species conservation crusade years ago, but suddenly returns to town. His first homecoming project: leading a protest against the airport construction and Ryonosuke's dad.
