Sloane and five other teens are trapped inside their high school during a zombie outbreak. Just one bite to kill you and reanimate you as a vicious creature without any sense of love, compassion, or remorse: only a hunger for human flesh. People have become erratic and sometimes Sloane doesn't know who to trust. The necessities of the group change drastically, everything turns for the worse, and their willingness to survive takes them to a new level. The dead know the living are inside the high school and it's only a matter of time before the dead get past the barriers until something happens that will change the group, for better or for worse.
