The Box.

An ex-con tries to go straight but also wants to get back money he's owed for the job that put him in prison. He meets a waitress who's also seen her share of trouble and they start up a tenuous relationship. Then there's a murder and things get complicated. It's noir so the plot isn't the main focus but the mood of the film is consistent and properly downbeat. The characters can't seem to shake the fate that hangs over them.
