Office worker Park Dong-won and his family move into a house he bought after years of saving. He throws a housewarming party for his colleagues, but heavy overnight rain leads to a gigantic sinkhole that engulfs the entire building. Hundreds of meters down the hole, with rain starting to fill it with water - survivors have very little time to get back to the surface.
