When Anne (Synnøve Karlsen) and Patrick (Luke Norris) hail a black cab after a night of drinking, their driver (Nick Frost) is talkative, even cheerful, but they are in no mood to talk. In fact, the two barely speak to each other. That is, until they realize that the driver has no intention of taking them home. Locked in the cab with no way to escape, the driver takes the couple to a stretch of deserted and supposedly haunted road. But what is he up to? Is he crazy or just evil? And why has he chosen Anne and Patrick as his victims?
