When Anne (Synnøve Karlsen) and Patrick (Luke Norris) hail a black cab after a night out, their driver (Nick Frost) is chatty, even jovial, but they’re in no mood to talk. In fact, the couple barely speaks. That is, until they realize the driver has no intention of taking them home. Locked in a cab with no way out, the driver takes the couple to a deserted and seemingly haunted stretch of road. But what is his purpose? Is he crazy or just plain mean? And why has he chosen Anne and Patrick as his victims?
