Based on the existence of "jjokbang", illegal separations within a home that are rented as small spaces that barely fit one person, this disturbing story is set in an indeterminate future to create a Kafkaesque reality. The film always suggests but rarely explains, which keeps it in a constant tone of uncertainty, even about what is real and what may be the product of emotional detachment. But it creates an environment so mysterious and at the same time so connected to certain realities that it manages to be a fascinating foray into social cinema through the springs of the suspense genre.
