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