When an alien ship hovered over the city, no one could even imagine what it could turn around. Gradually, to the spectacle in the sky began to get used. Moreover, besides the fact that this ship was hanging in the air, nothing more happened. Apparently the aliens just studied people.

Tsunami, earthquakes swept from the face of the earth many cities and their inhabitants. After that, people were struck by a terrible and unknown virus, and only a few survived after the third wave. People already understood that their death was only a matter of time, because the aliens did not plan to stop there. The fourth wave was the madness of the population. People began to fight with each other. Amid all this madness is a 16-year-old girl named Cassie, who lost her mother through the fault of the epidemic and the general insanity - her father.
