After an apocalyptic earthquake, the only remaining apartment complex turns into a market where survivors buy and sell whatever it takes to survive.

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.
