A virus strikes Chunan University of Arts and Sciences, turning the campus into a zombie purgatory. Ordinary college student Lin Chen and three roommates are trapped in their dorm, with no cheat systems and no supernatural powers, struggling to survive relying solely on supplies and crude weapons. They must fight bloodthirsty hordes of corpses, while also confronting the twisted human nature in desperate straits, peers looting supplies, temporary allies harboring hidden motives, and a survival crisis of scarce supplies. Across the street, Lin Chen's beloved Lin Xi and his tall girlfriend are trapped in the women's dormitory. The group wanders between life and death, taking desperate risks again and again to rescue companions, struggling amidst the entanglement of bloodshed and human nature, and guarding each other and the faint remaining glimmer deep in their hearts in the scarred campus.
