Welcome to the Pit-Stop Grill, a roadside attraction along Arizona's Route 66 where travellers kick up their feet while sipping a nice cup of joe. It's a cool oasis in an unforgiving desert landscape. It's also the last stop on the road to Hell. When ten people find themselves inside the eerie diner, unable to get out or remember how they arrived, all they know is what their waitress, Holly, tells them: a bus is coming. It will take them the rest of the way to a destination of unspeakable horrors. Led by highway patrolman, Officer Scott Alders, the group of strangers unite with a common goal--escape. Each of them holds dark secrets, but personal demons are no match for the wraithlike bus driver who arrives bearing the nametag RAMSEY. Driving an oily black bus with ghostly headlights and exhaust that smells of brimstone, Ramsey wastes no time picking them off one by one. As their number dwindles and the terror mounts, Scott Alders realizes it will take more than a police-issued sidearm to stop the evil that tracks them. But is there enough power in their battered spirits to combat a crimson-eyed driver with a schedule to keep? One thing is clear: you'll think twice before you make your next Pit-Stop.
