In 2006, in the United States and China, disaster struck, the advent of a dangerous and contagious virus. Alice was a researcher and a doctor. Alice had a coworker named Jimmy. Jimmy here is a researcher, they've been friends since they were in college. Alice was doing research on a virus, which was given to her partner when she was in China. Because in China there is sad news of a deadly but live virus spread. The results of this research into the zombie virus are from the South Pole which, there's a virus that comes out of ice freezing, probably because there's a little melting ice caused by global warming. The zombie virus spread so quickly, as early as Beijing had a peaceful peaceful environment transformed into a city with thousands of undead. Similarly, in Los Angeles, as a result of Alice's carelessness, Alice took a sample of the virus and fell in the river so that the spread of the zombie virus was spread in Los Angeles as well. Alice and Jimmy's studies are now so dangerous that they were traumatized to become researchers. Then they tried to save themselves and with effort, they succeeded.
