Title, please, of an obscure film (about nine years ago)

In one of those life imitates art moments, I’ve recently found myself experiencing the plot premise of a film I saw about nine years ago. The premise was that fifty dollars has gone missing from one the main character’s wallet (I’m missing the exact same amount, though not from a wallet) and the question is what happened to it. One focus of the film is how suspicion can affect attitudes with respect to all possible suspects, when of course only one can be the perp. Assuming there is a perp. Great little movie, btw, basically just four characters, a story and some dialogue. No FX beyond a little Foley work.

Anyone remember the title?

That’s it. Thanks.
