Madeline Monreal, a Biochemist, narrates her story several years after the initial virus outbreak. She recalls her days in high school during this post-apocalyptic era where life has been restored to normal, except for the kids carrying a mutated virus which can turn them into the undead.

As she retells her life including the beginning of the outbreak, we follow the aftermath of the initial incident as it spreads over the course of a grueling day and learn how each person pulls together the strength and resolve needed to pull through this ordeal or succumb to the wrath of the undead.
