When Anne (Synnøve Karlsen) and Patrick (Luke Norris) hail a black cab after a night out, their driver (Nick Frost) is chatty, even cheerful, but in no mood for conversation. In fact, the pair barely speak. That is, until they realize the driver has no intention of taking them home. With the taxi locked and no way to escape, the driver takes the couple to a deserted and supposedly haunted stretch of road. But what is his motive? Is he crazy, or just plain evil? And why has he chosen Anne and Patrick as his victims?
