After the city erupts in an outbreak of mass murder, a few survivors find shelter in an isolated dilapidated church. The government claims that the spreading chaos is the result of a biological terrorist attack, but the people in the church have theories of their own. Some believe that it's stem cell research gone mad. Some believe it's the wrath of God…and some are convinced that it's a surprise ground attack by another country as an act of war. In fact, the only thing that these people seem to agree on is that whatever afflicts their funny walking attackers isn't really important. The really important thing…is to survive, even if that means using fighting techniques learned from horror movies and music videos.
