Four middle school students, who are the members of a photography club receive an old-fashioned analog camera from their teacher. The teacher asks them to take pictures of 'the end of the world' during summer vacation. While they discuss where would be the end of the world, as one of the girls suggests, they just get on the subway to go to the very last station.

During a summer vacation, Ok-ju and Dong-ju move into their grandpa's house. While Dong-ju adapts to his new home, Ok-ju feels awkward about this new environment. Once their soon-to-be-divorced aunt also moves in, and as Ok-ju spends time with her family, the house and her grandpa start to grow on her.
