Animator Park Hye-mi did quite an impression in 2015, with her debut feature "The Crimson Whale" about an orphaned girl trying to make a living in a dystopic setting. "Scarecrow Island" is her second work, a short this time, which moves along similar lines.
After a massive nuclear blast, almost all of humanity suffered from terminal illnesses. The few that survived managed to escape and create a safe space to live in. The only living creatures that remain on the rest of the land are monstrous non-human life forms. Humanity is now trying to regain these lands, but in order to do so, the army has asked every parent to turn every children older than 5 over, in order to be trained as pilots, promising some vague privileges once the lands are reclaimed. The main protagonist of the film is one such boy turned pilot, who, in one of his flights, spots an undamaged island, which seems to be populated by people. The boy becomes obsessed with the island.
