I am trying to find the title of an old movie: Two college female friends, one black and the other white, travel across country. They were stopped in a small town by the local sheriff and thrown in jail. The white girl was given special treatment, however, the black girl was raped and beaten and left hungry.

I am not sure about the ending, but that is the gist of the movie.

Sounds like Nightmare in Badham County (http://www.imdb.com/title/tt0074967/)

Instead of just disagreeing, maybe you could add some more details, for instance what does "old" mean? 70's, 80's...

We are not mind readers, nor are we walking encyclopedias of movie trivia. WE GIVE OUR TIME , freely I might add to help you find your stinking movies. Then you disagree! STFW and find them yourself. You might want to give more details the next time... KIT

THIS is not how you get the answer to your question. You'll get no help from me with this attitude.
