The end of the world is coming, and the world is threatened by white shadows and mutant creatures. The survivors struggle to survive in a shelter. During a patrol, Lin Ye, Su Xiao and others accidentally discovered that the radio in the abandoned signal tower actually received the signal of the "Northern Joint Base" - not only is it a large safe area that can accommodate 5,000 people, but it also has sufficient food, medicine and weapons.
On one side is the existing shelter, which is increasingly scarce in supplies and full of dangers. On the other side is a distant base that is full of unknown dangers but holds hope. After debate and decision-making, the fifty-six survivors decided to abandon their familiar shelter and embark on a half-month migration. They took the elderly and children, held simple weapons in hand, supported each other in the apocalyptic wilderness, and headed towards the coordinates of 38°15′ north latitude and 115°20′ east longitude, just to find the possibility of survival and the glimmer of rebuilding their homeland.
