Once a month - for one hour only - in one random American town, every vehicle comes alive. More than alive - possessed and intent on killing everyone in its path. Into this chaos comes a band of escaped convicts and a small group of apparently scientific...priests? Are the killer cars a sign of the end-times - a message from hell? Or is the whole event a technological fake orchestrated by a shadowy conspiracy?  Or is the truth even crazier? Join our group of scientists, criminals and head-cases as they attempt to survive the carnage and work out what the hell is going on (or if hell is actually going on!).
