Amid a sudden global ecological catastrophe, a couple travels 1,200 kilometers from Donghai City to return to Zhang Chen's ancestral home in the mountains of the southwest. Their journey is more than a trek across the land: it is a crucible of human nature, trust, and the will to survive. And what awaits them at the old house is more terrifying than the apocalypse itself.
Main characters:
Zhang Chen (28): A mechanical engineer, practical and decisive, with wilderness survival skills. He carries unresolved issues with his father, and his hometown is both the place he wants to escape and the root he is ultimately forced to return to.
Lin Wei (26): A middle school art teacher, sensitive and delicate, and prone to relying on others. In the face of desperation, she gradually awakens to her own resilience, though she is deeply uneasy about the unknowns surrounding Zhang Chen's hometown.
