After a freak accident, the dead came back to life as unthinking and unfeeling zombies, feasting on the flesh and organs of the living. Most were eaten or infected, but those who survived began working on a way to end the apocalypse. And after thirty years, someone finally did. A cure was made and distributed worldwide, allowing for those infected to become human once again. Five years after the main cure had been distributed, Erina Fiscella discovers something that could mean the end of the world for a second time. With no memories to guide her, she must turn to those responsible for the cure for help.
