It all started three days ago when Tom Keller (Daniel Buder) accidentally hit a passerby while driving. After getting off the car, he found that the other person behaved strangely, and the surroundings seemed to be in an inexplicable panic. Some people seemed to be infected by some strange virus and turned into bloodthirsty zombies, attacking every innocent passerby crazily. Tom was panicked and hid in the American base where he often played in his childhood with much-needed supplies. After more than ten days of squatting, he found that the zombies had changed and his ammunition was about to run out. For this reason, he had to go outdoors to explore the development of the situation. In a town, he accidentally found several survivors who were not infected. Tom joined these people and gradually learned that everything was caused by a virus developed by a biochemical company, which can transform the DNA of organisms. When the whole world has fallen, how should this group of survivors find tomorrow...
