In 2025, a strange low-frequency event strikes a city park.
Sun Moyu, a socially anxious young man, narrowly escapes an attack by an African caracal while walking his dog. Then he discovers that animals across the city are going on a rampage.

What world-shattering truth lies behind this animal awakening?
