Zhao Daqiang, who became abruptly rich from demolition compensation, monopolizes the community rooftop for a late-night party, causing noise pollution, blocking the fire escape, smashing rights-protection lawyer Lin Xiaoyu's phone, and even slandering veteran Grandpa Li who stepped in to stop him as a scammer staging a fall. Property Manager Wang, mindful of Zhao owning multiple apartments, blindly plays peacemaker. Warm-hearted Auntie Song teams up with Lin Xiaoyu to pick up the Civil Code and Fire Protection Law to gather evidence and defend their rights, cleverly using a fireworks standoff to awaken the other party. Zhao Daqiang, in annoyance, blocks the rooftop escape door, ultimately causing a fire by illegally rigging wires, trapping the entire building in a dangerous plight. After the fire incident, all homeowners jointly hold him accountable. Witnessing his son envy the warmth of the neighbors, Zhao Daqiang lets go of his arrogance, signs the rooftop convention, and takes the initiative to make up for his faults.
