Finding a movie: man lays in bed with woman

I’m sorry in advance, but i have a brief description; i don’t remember anything else from the movie.
Here we go: A man lays in a bed with a woman (they just had sex??), another man comes in the room, throws a knife to the wall/pillar, the knife sticks in the wall/pillar and the man lays in bed next to the woman and man.

That’s it. I hope you all can help 🙂
