A virus accidentally unleashed in a small town in Colorado turns people into zombies while the Army tries to quarantine the area and keep it from spreading. The local hospital is overrun, as are the main roads, and the few survivors try to find a way to safely escape from the hordes of fast running zombies.
While the survivors keep their wits for the most part, there are a few moments designed to add suspense where they do things totally out of character. This may also be the only movie to have a vegetarian zombie in it.
I'm not sure why people remake movies, especially when generally they make a worse version of whatever they are re-making. I suppose this has a bigger budget than the original, but unless you prefer the running zombies, stick to the original 1985 version.
