Three friends find themselves trapped in an underground parking garage. They soon discover it is no ordinary parking garage with doorways leading into the past and future and floors that repeat themselves for eternity. As their perception of time and space crumbles around them, they must struggle to keep their sanity, if not their lives.

A bus full of strangers find themselves fighting for their lives when one of them reads from an ancient Gothic tome, bringing six dead serial killers back to life, who proceed to hunt them down one by one.
