Do you know the name of this weird murder movie?

Here's what I saw: It starred 2 guys & a girl in their 20's. They were obviously foreign due to their accents. I can't remember the accent but it was definately somewhere in Europe. And I guess they killed some people and they ended up with a TON of money. And the money ended up tearing them apart. Like, the couple (the older guy and girl) were plotting against the youngest boy. Then, the oldest guy in creepy glasses and a side part tried to leave with the money while the girl was sleeping. But she caught him. And then he retaliated by telling her that he secretly knew she had bought two plane tickets for herself and the younger guy. And then she stabbed creepy older guy in the throat. And then when the young kid thought everything was solved she stabbed him and took off with the $. But young kid had the last laugh-he didn't die and had actually cut newspaper into squares to replace the bills in the suitcase. The camera then zoomed to show the $ beneath the floor under him.
