Lin Wan, an investment manager, lost her wheelchair-bound father, her young daughter, and her beloved dog in her previous life when a fire broke out because an electric bike was illegally charged in her apartment building's hallway. The neighbor responsible framed her, and she died with unresolved hatred. Reborn just one hour before the fire, she desperately tries to stop her neighbor from pushing an electric bike inside the building to charge it. However, she faces resistance and ridicule from the unreasonable neighbor Li Meihua and her daughter, the arrogant repairman Liu Dahai, and the dismissive property manager Zhou Xiaomei. Lin Wan refuses to give up and seeks help from the community authorities at every level while urgently evacuating her father and daughter. She even sells her home at a low price to get her family out of danger. Although the fire eventually breaks out again, this time she races against time to evacuate the residents, and her entire family survives.
