A blizzard makes the hidden heating hazards in an old residential compound erupt all at once. While upstairs residents freeze, Guo Guifen on the first floor refuses repairs out of fear that her renovation will be damaged, and demands high compensation. Facing the plight of a sick pregnant woman and anxious neighbors, Lin Yuan, a sixth-floor designer, calms the impulsive Liu Gang, and discusses alternative solutions together with the maintenance master, the building head, and the community. A dispute centered around the heating pipes reflects the relationship between personal interests and public responsibility, and also shows the strength of ordinary people persisting in rationality, mutual solidarity, and jointly guarding a warm life in adversity.
