In this film, a group of friends come out of a club or similar establishment and proceed to the parking lot to go home. As they get in their car, it won't start up, and suddenly a shadow or similar creature comes out from underneath the car and starts attacking them and killing them one by one. Their only hope is to survive the night and be able to walk or drive away. I have searched high and low, and no one seems to have seen it. Please help!
