This was a movie that came out awhile ago about a girl in her 20's who is released from a prison in Maine and gets a job as a waitress at a diner. It is owned by an older woman(?? ) who gets sick, and eventually the girl takes over the diner.
There is a part where the older woman isn't sure if the girl can be trusted, as there is some money missing, but of course she didn't take it. Really good movie.
