With construction of the city’s brand new high-rise apartment building finally complete, Officer Yoon Sae Bom (Han Hyo Joo) is eager to move in. Having long dreamed of the day she could settle into her new apartment, Sae Bom is beyond thrilled to finally be able to have a place where she can comfortably escape the rigors of her job as a member of one of the city’s special police squads. With her long-time friend and fellow officer, Detective Jung Yi Hyun (Park Hyung Sik) moving in as well, Sae Bom is convinced this new home will bring her all the happiness she desires. Unfortunately, that happiness doesn’t last long. As a new type of infectious disease slowly begins to spread throughout the building, the residents soon find themselves the object of terror and a source of city-wide panic. With no other way of containing the disease, the residents are soon cut off from everyone and everything around them as the building is sealed off from the outside world. As the world around them struggles to make sense of what is quickly morphing into a full-on apocalypse, the uninfected residents' only chance of survival rests solely in their own hands. Confused, isolated, and terrified, the residents have no choice but to find a way to overcome their distrust of each other, as it’s their only hope of surviving this living nightmare. But how can they do that when it seems at least one of them holds the secrets that could either save or destroy them all? Set in the not-so-distant future, “Happiness” is a 2021 fantasy action thriller drama directed by Ahn Gil Ho.
