Penny Dreadful
Penny Deerborn (Rachel Miner) doesn’t like cars. I mean she really doesn’t like cars. Through a series of flashbacks in the movies, we find that she was in a horrible wreck when she was younger that killed both of her parents (at least, they appear to be her parents). So her psychiatrist, Orianna Volkes (Mimi Rogers) is helping her through the process of conquering her fears.
Orianna has written at least one book on the subject (we see it several times as events of the night unfold), and she is helping young Penny to come full circle. To conquer her fears by confronting them. So they are taking a ride into the mountains. It appears that the mountains might be the place where the wreck happened, but that may or may not be important. What is important is that Penny simply doesn’t like being in cars. She gets sick just riding along with the door shut.
