When a deadly virus outbreak causes people to turn into flesh-eating zombies, a group of survivors must fight for their lives and find a way to stop the infection from spreading.

The United States Government has developed a highly effective nerve gas that is unleashed upon the residents of a small Maryland City. During the top secret exercise the infected citizens begin to convert each resident into a sort of living zombie, until the remaining town residents, 6 total strangers, are trapped inside a movie theater cineplex.
