"Cash" is a fun little film. Money falls from the sky in a suitcase on some guys car. Of course he should turn it in. Of course he shouldn't spend it. He keeps it, he spends it. He and his wife are finally feeling a bit of good luck.
Then the guy who has been given the job of getting the money back shows up. He's polite enough, but very insistent. Not only does he want the money they haven't spent yet back, but he wants them to pay the balance of what they did spend. Of course they don't have it, but it's wonderful what a motivational talk from a guy with a gun can do.
A cute, small, dark tale of why it is always better to listen to the angel on your shoulder.
