I would say go by pretty much what other positive reviewers have said here. You have a very clever little story which creates a very palpable sense of Mystery. You truly wonder what the hell is going on, along with our befuddled protagonist.
If the writing were not as sharp, I don't know if the story would have been nearly as effective. At first, you might think that the 'suitcase' is just a McGuffin (as in the outstanding and unusual 1955 Noir Classic 'KISS ME DEADLY' by Robert Aldrich - Isn't that just THE greatest title!) But, not giving anything away, by the end you actually do know what is going on.
The interplay between the characters is really what makes this movie shine. They both are quite good. At first, it kind of has a slightly similar tone to the also excellent Scorsese film 'AFTER HOURS', but far simpler and much more stripped down without all the Surreal characters and situations.
The idea of the story I feel is quite clever, and the way it is told is actually very straightforward and simple. But, when you get to the end, it has a nice punch. I'm NOT going to give away a certain element that is in this film because I see how it is listed Genre-wise and I don't want to spoil it. But, I will say that in all my profound cleverness I did guess somewhat along the lines of what was happening : )
So, if you like a nice, short, clever, sometimes humorous, fast paced Crime/Thriller, but with a very Mysterious twist, most definitely give this one a go!
