When I was quite a bit younger, I remember seeing part of a movie. The part I remember involves a dad letting his teenage daughter go to a party, but makes her promise to call him if she needs a ride. She ends up wanting to go home early and the friend she was supposed to go home with wants to stay or she is too drunk or something. The girl is going to call her dad when a Guy offers her a ride and she decides not to wake her dad. The Guy drives and goes to a place that isn't her house. When she comments that he needed to make a turn or whatever, he locks the doors so that she can't get out of the car. This is when my parents said I had to leave the room and wasn't allowed to watch. I was maybe 10, now I'm 21 and I still really want to see this movie!! Any ideas?
