Willow, a genius 15 year-old, travels to Colorado from New York for a gaming convention that she's invited to for selling t-shirts and meeting some of her fans.

However, in America they have discovered that some people were stupid enough to eat from infected animals for testing and started another zombie-like infection across the nation, and spreading throughout the world as well.
