Li Li is a climate and environmental scientist with ten years of experience. Through research, she discovered that climate change in the past 50 years is expected to lead to an apocalyptic environment where the temperature will suddenly drop to minus 100 degrees in three months. By then, food, housing, transportation, and health will be greatly affected. She first contacted the government department to report the deterioration of the climate. The government attaches great importance to preparing for expert talks. Although conservative representative Wang Yuan has rich experience in climate work, he does not recognize the end of the world. He tries his best to prevent alarmist talk when he thinks the end of the world is nonsense. Preparatory work will bring unnecessary waste. Climate change does not happen overnight. Although Li Li argued hard, the people she could persuade were too conservative and distrustful. Li Li went home to discuss preparations with her husband Zhang Cheng and son Zhang Yu.
