Ten years after the zombie apocalypse, civilization is in ruins. Su Hui, a former kindergarten teacher, was the most useless "liability" in the settlement until she discovered a young child in the ruins who was about to mutate but remained awake. Violating the iron rule of "clearing infected bodies", Su Hui hid the children and successively took in more abandoned "Future Fire". She used broken toys and faded picture books to build a secret nursery in the wasteland, guarding the faint light of civilization. However, when the children's secrets - that they may carry virus antibodies or hold the key to human evolution - are exposed, Su Hui and her little shelter instantly become the targets of competition and destruction by all forces. In this wasteland where the weak are preying on the strong, how can a helpless kindergarten teacher use knowledge and remaining goodwill to protect the last hope and become... The initial torch for the restart of civilization?
