Anne (Synnøve Karlsen) and Patrick (Luke Norris) hail a black cab after a night out when their driver (Nick Frost) is chatty, but not in the mood to talk. In fact, the couple is on barely speaking terms. That is, until they realize the driver has no intention of taking them home. Locked in the cab with no means of escape, the driver transports the couple to a supposedly deserted and haunted road. But what is his purpose? Is he crazy or just evil? Why has he made Anne and Patrick his victims?
