A female scientist of a biochemical company found a clay pot containing ancient seeds during archaeology, and she handed it over to an experienced old doctor. After research, the old doctor used the seeds in the jar to cultivate a plant with magical healing function. However, Kyle, the assistant of the female scientist, secretly brought out the seeds in an attempt to make money by trading with a mysterious organization. Their trading process was filmed by two journalists, whose intervention interrupted the transaction, and the ancient seeds fell into the ground in chaos. When it comes into contact with the land, the seeds quickly take root and sprout, and soon grow huge roots. Like a virus, the roots of plants spread rapidly, destroying all the facilities and buildings encountered along the way, and countless people lost their lives in this unexpected disaster. The CIA and other security departments are involved in the investigation, but no matter how fierce the firepower is, it cannot stop the spread of terror.
