In a world devoid of most plants and animals, a giant wall, vertically across the globe, such that its tail and head meet, divides the world into two parts. One side for nature, and the other for humans. An organisation, however, uses the nature side for experiments in biotechnology. The result? Flying dinosaurs, sentient trees and super-muscular apes. The humans don’t know jack about what lies on the other side. They just believe, that they have made the greatest sacrifice to nature by dividing their world in half.
Then one day, a virus that turns humans into parasitic hosts starts spreading, zombifying the population living close to the Wall. Would the youngsters on the Human Side be able to cross the Wall and try to find a cure? Is it really even a virus...or is it one of the experiments gone wrong?
