In a version of 1970s Seoul where apartment blocks rise like landmarks of progress, the city’s story takes a harsh turn from progress to catastrophe. The skyline has already shifted to concrete towers and skyrocketing prices, but by December 2023 an unprecedented cold wave and a massive earthquake flatten most of it. Out of the wreckage, one building survives: the Hwang Gung (Imperial Palace) Apartments, a place that becomes both sanctuary and prison for its inhabitants.
Within this lone refuge, the lives of a few survivors begin to converge. Min-sung wakes up to a gray world where power and water are gone, and contact with the outside is severed. His wife, Myung-hwa, shares the burden of adaptation as they tentatively reestablish routines in the ruined rooms. When a mother and child from a neighboring collapsed unit come seeking shelter, a test of mercy arises. Though uncertainty gnaws at him, Min-sung is swayed by Myung-hwa’s compassion, and they open their doors to strangers, attempting to preserve some semblance of humanity amid the collapse.
As days pass, the fragile calm gives way to a harsher truth: survival appears to demand a new, brutal morality. The community begins to barter for scarce resources, and the fear of outsiders mutates into open hostility. Tensions escalate, and a deadly clash erupts at the gates as outsiders press for access to food and safety. A fire breaks out, and a figure of quiet courage steps forward: Yeong-tak, a man who risks his life to extinguish the flames and earns the admiration—and the political capital—of the residents, eventually becoming their leader.
Under Yeong-tak’s uneasy leadership, the residents vote to expel outsiders, framing the measure as a necessary act of survival. The outsiders push back, and a brutal confrontation at the apartment gates reveals how quickly order can fracture into control, fear, and violence. What begins as a siege evolves into a reshaping of the complex into a seemingly utopian enclave: strict rules, labor-based food distribution, and patrols that claim to protect the community. Yet the veneer of order masks a growing cruelty. The patrols plunder nearby shops and beat survivors, and the city’s inhabitants begin using a dehumanizing term for the outsiders: “cockroaches.”
Hidden tensions simmer just beneath the surface. Myung-hwa learns that some residents, including Do-kyun, are quietly sheltering refugees inside the building’s walls, a dangerous act that could shatter the fragile peace. The arrival of a former resident, a woman named Hye-won, unsettles Yeong-tak and stirs memory and resentment within the group. Her presence challenges the delicate balance of power and tests the legitimacy of the new order.
As the community settles into its manufactured stability, the truth about Yeong-tak begins to emerge. In reality, he is not the man everyone believes him to be: a taxi driver who had been scammed while trying to buy an apartment in Hwang Gung. On the day of the earthquake, he confronted the real Yeong-tak and killed him, then assumed the dead man’s identity to survive. The impostor’s secret festers beneath the surface as Myung-hwa and Hye-won uncover the corpse of the real Yeong-tak hidden in his old unit, exposing the ruse and shattering the illusion of control.
chaos erupts as the façade collapses. Yeong-tak reacts with fury, killing Hye-won in a burst of rage, and the building is soon besieged by organized outsiders. A violent battle rips through the complex, explosions tear through walls, and many residents fall, including Yeong-tak himself. Min-sung and Myung-hwa manage to escape the collapsing structure, their world reduced to rain, rubble, and a smeared memory of order that could not endure.
Wandering the devastated landscape, the two survivors find shelter in a ruined church. There, a quiet moment of humanity lingers: Min-sung gives Myung-hwa a hairpin—an emblem from their scavenging days—and, injured though he is, dies from wounds sustained during the night’s chaos. Myung-hwa buries him with the help of other survivors, who invite her to join their community in another collapsed apartment building, a fragile offer of belonging amid a fractured city and a shattered dream of safety.
This is a story of how quickly systems that promise safety can become mechanisms of fear, how compassion can bend under pressure, and how, in the wake of catastrophe, people cling to fragments of hope while the world around them burns. It’s a stark meditation on resilience, identity, and the thin line between order and cruelty in a city that has already seen too much.
