Rhea, the protagonist, is betrayed one after another by her neighbor, cousin and ex-boyfriend during the zombie apocalypse, and eventually perishes in the horde. Unexpectedly reborn one month before the virus outbreak, she draws on her bitter memories and hard-earned survival experience from her previous life to secretly stockpile supplies, renovate her apartment into an impregnable safe house, and arrange for her parents to stay in a secure sanatorium to evade the coming disaster.
When the virus breaks out exactly as she predicted, Rhea defends her safe house with meticulous preparations. In the brutal end times, she rescues the orphaned girl Carrie, allies with the upright veteran doctor Jody and his grandson Hunter, and confronts Houston — the ruthless security chief who seeks to dominate the residential building and seize all survival supplies.
As clues surface, Rhea discovers that the source of the catastrophe, Project B-1127, is closely tied to her parents’ scientific research. After surviving multiple life-or-death crises, Rhea and her companions are finally rescued by the military. She reunites with her parents, and the full truth behind the virus leak is exposed.
In the aftermath of the disaster, Rhea founds the "Dawn" mutual aid foundation to support fellow survivors. She preserves humanity’s kindness and warmth amid the ruins, and achieves her own true rebirth and redemption.
