When huge meteorites rained through the sky like sharp knives falling from the sky, the earth ushered in a disaster. Volcanoes erupted collectively, hot magma swallowed the earth, tsunamis roared and flooded coastal cities, and the world was instantly enveloped in volcanic ash and despair. In a valley covered by thick volcanic ash, people who had never met before gathered here due to their survival instinct. Among them are doctor Lin Wei, engineer Chen Feng, and all kinds of survivors with different stories. Faced with the dilemma of lack of resources, constant aftershocks, and unknown dangers lurking, they must put aside their barriers and use the limited resources in the valley and their own skills to build a temporary shelter. On this piece of ashes, they use unity and tenacity to fight against the haze of doomsday and struggle to survive.
