Phoenix Laboratory, a premier modern-day organization ostensibly dedicated to saving humanity, is in reality a hotbed of internal corruption and factional infighting. Evelyn, a core researcher at the lab, possesses a unique ability: she can transfer the "calamities" afflicting others onto herself—at the cost of her own lifespan. When the zombie apocalypse erupts, she is betrayed by her fiancé, Adrian, and her colleague, Serena, who push her directly into a horde of the undead. Reborn 30 hours before the outbreak, she uncovers a shocking, two-decade-old secret known as "Project Noah," involving Phoenix, the Vale family, and a mysterious organization called the "Dawn Society"—and discovers that she herself is the "key" to this apocalypse.
