It is the year 2049: amid dry land, constant fires, typhoons and tsunamis engulfing the site, and new diseases every day, humanity has declared Earth uninhabitable. The only person left is Yoon. She is supposed to record conditions on the planet and see when humanity might be able to return. The rest of humanity is on board an air raid shelter that orbits the moon and waits for the day to live again on Earth. The huge data storage room called ‘Black Box’ on Earth records and stores the history of planets and humanity. The person who resides in the Black Box is the ‘recorder’. Yoon, the first recorder, has sent her 6-year-old daughter to an air raid shelter and guards the Black Box center alone. ‘I hope to return to the air raid shelter quickly and live with my daughter on Earth, but the state of the Earth in 2054 is not that good.’ Meanwhile, she accidentally sees a video of the ‘Climate Crisis Archive Concert’ left in 2023 by musicians … Will Yoon have faith that mankind can coexist with the Earth?
