High schooler Daisy Willis and her friends manage to escape from their school after it got overrun by zombies. The virus that seems to be infecting the people is called Nature's Vengeance and it makes the nice people in her small town extremely violent, with cannibalistic tendencies. Even thought they don't want to admit it, the virus turns people into real life, honest to god zombies. Now, Daisy and her ragtag group of friends, some from before, and some she met along the way, have to try and survive in a world that is trying to destroy itself.
The world is still reeling with the aftermath of the failed biological experiment which was engineered to enhance human abilities but ended up destroying the human race. The group that it through are now trying to find the normalcy in life again only to be thrown into a new nightmare altogether.
A group that knows more than anyone should has their eyes on the survivors and virus, convinced that they can use this to their own advantage and create a strength of their own.
Old memories resurface, dangerous risks are taken, unexpected reunions occur, and blood spills all over as the survivors battle to survive not one, but two nightmares together.
