Year 2019, The Philippines is heavily infected by an unknown virus which leads into the almost-extinction of the Filipino Community. The virus was accidentally created by a well-known Spaniard corporation which made an experiment called "Misión: Pacientes Con Cáncer". This experiment aimed to end the sufferings of cancer patients. Instead of curing the sickness of the patients, its failure caused a major problem in the Philippines. Other countries have locked up their gates for the survivors, and one of them being Zaina Alcantara. Zaina is one of the survivors when an epidemic breaks the quiet life of her and the whole Philippines. An epidemic that may end the existence of all human beings. Would she and the survivors end this epidemic, or would it do the other way?
