This movie was possibly a female assassin movie, but maybe not. I believe it was set somewhere in Europe. I remember a scene where the female lead hides in a closet of another woman’s apartment and watches her sitting at a table contemplating, attempting or committing suicide. I think a bathtub comes into play. In the climactic scene a crystal or some other shiny object that was hung from the mirror of a delivery truck earlier in the movie catches the light in just the right way to temporarily blind someone which then results in the bad guy(s) being killed instead of the lead or possibly her girlfriend. I think someone ends up being impaled. I also remember that the film shows both possible outcomes.
I don’t remember anything about the title, actors or director.
