I was asked for the name of a good horror film, and after a while, I remembered a film I saw a couple of years ago. The problem is that I can't remember what it was called.

There was a women, I think she was a psycologist, who started looking into a case. A serial killer had cut of the fingers of his victims that we're all children.

I can't remeber to much more, I think the woman got her finger cut of as well, but I'm not sure.
If anybody knows the name of this movie I would be eternaly greatfull if you could help me.. :0)
