Deadlands 2: Trapped 2008

In one night, One city will fight against an enemy that never stops, shows no emotion, no remorse, and is already... DEAD!

Directed by Gary Ugarek

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.
