When Anne (Synnøve Karlsen) and Patrick (Luke Norris) hail a black cab after a night out, their driver (Nick Frost) is talkative, even jovial, but they’re in no mood to talk. In fact, the couple barely speak to each other. 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 deserted, supposedly haunted stretch of road. But what is his purpose? Is he crazy or just plain evil? And why has he chosen Anne and Patrick as his victims?
