I saw this movie before 2005. It was based in current times. There was a scene were there was what looked like a castle, maybe a modern one, there were masked people watching frm a balcony, below there was a big hall with many women standing in a big circle, what seemed to be a disguised guy chose one and hit the floor, then that woman could be seen having sex with what I loosely think it was a client?

That’s all I can remember. I’d appreciate any hint to find that movie.
