A global unknown mutation has caused a collective awakening of animals on the earth. They are no longer the docile or ferocious instinctive creatures in the eyes of humans, but have intelligence comparable to humans and superior physical abilities. The city fell in a short period of time, the reinforced concrete jungle became a hunting ground for animals, and human civilization was on the verge of collapse. Zoologist Lu Mingyuan and former special forces member Su Qing lead a team of survivors to survive in the ruins. Not only do they have to avoid being hunted by mutated animals, but they also have to solve the mystery of the sudden mutation of animals, and in despair find a way to coexist with these "new owners", or find a glimmer of hope to reverse the catastrophe.
