When Anne (Syunjeve Carlsen) and Patrick (Luke Norris) hail a black cab after a night out, the driver (Nick Frost) is talkative, even cheerful, but they are in no mood to talk. In fact, the couple barely speaks. That is, until they realize the driver is not going to take them home. Locked in a cab with no way of escape, the driver takes the couple to a deserted and supposedly haunted stretch of road. But what is his purpose? Is he crazy or just evil? And why has he targeted Anne and Patrick?
