Chloe Weathers is a normal eighteen year old high school girl. At least, that what they think. Really, Chloe Weathers is a genius who works as a scientist in the testing labs. But one day she goes to work and finds someone let out a deadly chemical, turning everyone inside into 'Flesh-Eaters'. To keep the labs illegal bioresearch from leaking out to the public, Chloe and the ex army soldier, Daniel Collins, along with other survivors, must destroy them all before any escape into town. But who let it out in the first place?
