I sae a small part of this at a friends house on TV, so i dont know if it was tv series, a made for tv movie, or a movie on tv, and i also dont know if I saw the begining, middle, or end. The part that I saw was this regular guy picks up this hitchhiker and the hitchhiker pulls a gun on the guy and tells him to do something, but the driver doesnt want to so he crashes the car and flipps it upside down, in atempt to kill the hitcher, who is not wearing his seatbelt. But its all in vain, because now the hitcher is laying on the bottom of the car, unharmed while the driver (wearing a seatbelt) is susspended upside down in his seat, helpless. The hitcher is about to shoot the guy but then something knockes them both out. A wind up teeth in a paper bag in the back of the car crawls out. When the driver wakes up, its night and he sees the teeth dragging the corpse of the hitcher away.
Id like to see the rest of this one, but I need to know the title. Any ideas? Guesses?
