83 Hours 'Til Dawn (1990)

The fact that this actually happened (to Barbara Mackle, who wrote a book about her experience that this movie is based on) makes it even creepier. And the fact that the man who kidnapped her is now a doctor (Gary Steven Krist) is frightening. The fact that he thinks everyone should forgive and forget (and even wrote a book of his own) tells me that he has no idea what he did to that girl or what could have happened to her. It's been a while since I saw the movie, but watching it gave me the creeps, thinking that someone could do that to another person. Good movie.
