Thirty-two-year-old ordinary migrant worker Chen Mo, his wife Lin Wan, and four-year-old son Xiao Le spent all their money to finally own a house of their own in the city. They thought this was the beginning of a happy and stable life, but all the happiness was shattered by the endless noise and unreasonable attitude of the Zhang Jianjun family upstairs. From being tolerant and considerate at the beginning, to his child being disturbed by the noise and running a high fever, and even being viciously insulted by the other party in public, Chen Mo tried to find mediation with the property management company and call the police to deal with it, but he repeatedly ran into obstacles. The indifference and perfunctory response of the property management company completely left him heartbroken. In order to prevent his children from growing up in an environment of hostility and quarrels, and to prevent their childhood from being polluted, Chen Mo resolutely decided to sell the house at a loss and move away despite the criticism of being a "coward" and "worthless". It seems to be an escape from bowing to evil neighbors, but in fact it is the most tender protection of a father and a husband for his family. And those wicked people who act recklessly will eventually end up "receiving their own consequences." This is a story about real-life conflicts between neighbors, and it is also a reflection on life about choices, responsibilities and true strength - true bravery is never about fighting with bad people to the end, but about knowing how to put away your edge for the people you care about and protect the most precious warmth in life.
