The world has been reduced to rubble by a massive earthquake. While no one knows for sure how far the ruins stretch, or what the cause of the earthquake may be, in the heart of Seoul there is only one apartment building left standing. It is called Hwang Gung Apartments. As time passes, outsiders start coming in to Hwang Gung Apartments trying to escape the extreme cold. Before long, the apartment residents are unable to cope with the increasing numbers. Feeling a threat to their very survival, the residents enact a special measure.
Unfortunately the movie Concrete Utopia is not yet available on HBO Max.
