Strangers on a bus find themselves fighting for their lives when one of them reads from a Gothic book and brings to life six dead serial killers who proceed to hunt them down one by one.

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.
