Overview: When a drug to replicate plant cells creates a sentient form of flower, the planet is over taken by flora and humankind is depleted. A Chinese task force, a widowed father and his young daughter fight to survive in a mission to inject an antidote to the core of the plants to reverse their growth. In order to combat desertification, humans have developed drugs that promote the accelerated reproduction of plant cells, but they have accidentally liberated the stress system of plants and awakened plant emotions. Over-reproducing plants quickly engulfed cities and attacked humans. A global event that could lead to the disappearance of human civilization. The green tide is about to hit, and the global joint action team is deployed to implement drugs that inhibit plant activity. The Chinese team and survivors meet in danger, travel through the ruins of the city, and work together to complete the difficult task.
