Hana, the protagonist, lives in a small box-like room and interacts with the world only by listening through the thin walls that separate her from her neighbors. Hana is consumed by thoughts of death, only to be confronted by an unexpected death. In the film, Hana's internal struggles are portrayed through an intensive use of cinematic languages, such as character's movement and offscreen sound, instead of exterior action-oriented events and verbal languages. A character is shown, but not explained; suggested, but not forced to be "read" or “understood.” The room itself acts as an antagonist; the limited space and sound has the power to manipulate human emotion. It is a film for people who are fiercely fighting with their inner selves, isolation, and the weight of life.
