In 2063, a strange dark red aurora swallowed up the starry sky of the Arctic Circle, and the ensuing meteorite impact left an ominous mark on the ice sheet. Astrophysics graduate student Chen Xinxin and her companions were the first witnesses to encounter a strong electromagnetic pulse attack and fell unconscious on the ice sheet, leaving strange unexplained red lines on their foreheads.
At the same time, the small town far away under the aurora is quietly falling into a silent terror. Police officer Tang Long discovered that the toys in the town seemed to have independent evil lives: plastic soldiers fired guns, rag dolls opened their mouths to bite, remote-controlled planes dived and exploded... A bloody nightmare spun by children's fun suddenly unfolded.
As the investigation deepened, Tang Long, scientist Professor Wan Li and others discovered that all mutations pointed to a mysterious extraterrestrial energy called the "Red Net". It can assimilate electronic devices and biological genes, turning ordinary toys into killing machines. What is even more desperate is that the police chief An Pingqing, who is supposed to protect the people, seems to have already co-existed with the red network and is secretly executing a global harvest plan called "The Sower".
From toy stores and squares to rivers and police stations, the fighting continues to escalate. Human beings are not only facing out-of-control toys, but also the fate of themselves being transformed and assimilated. When the red signal tower is erected in the town and the global harvest process is launched, the survivors must rise up against the embers of civilization and fight the last battle for the survival of mankind.
