When Anne (Synnøve Karlsen) and Patrick (Luke Norris) take a black cab after a night out, their driver (Nick Frost) is chatty, even cheerful, but they don’t feel like talking. In fact, the couple can barely talk to each other. That is, until they realize the driver has no intention of taking them home. Locked in the cab with no escape route, the driver transports the couple to a deserted and presumably haunted stretch of road. But what is his goal? Is he crazy or just evil? And why did he choose Anne and Patrick as his victims?
