This cloud contains an alien virus that infects 1/3 of the worlds population. At first it only sickens, but soon mutates turning its victims into blood-thirsty zombies intent on spreading the virus.

Struggling to save family and friends, the young men must embark on a cross country trip to safety. Upon arriving they find zombie and human alike intent on their destruction.
