Hello,
I’m searching for quite a while for the name of a horrormovie, I saw on youtube some years ago and maybe you could help me find out the title of it.
I saw the movie in German but I’m sure that movie is available in English too.
The film itself is in color and cannot be that old. I would guess somewhere between 2000 and 2010.

Plot
The film is about an enginner or mechanic and his wife moving in a car workshop somewhere in nowhere. They live in a caravan on the property. On the property appears around three times in the movie the ghost of a murdered woman. The man falls at a point from the caravan and got knocked out. After he awakes his wife is missing. He finds a live videostream in the workshop from her held captive with removed arms. He finds them in a shelf. The guy who has captured the wife is a fat bastard and wants the man to torture and kill people on the property while installed cameras are streaming the kills to the fat guy. At some point the husband got his face complete destroyed and builds himself a metalmask with small lights. After that I remember only a scene where a woman finds a man lying on a worktable with a cage around his head and a cutted of leg with a large screw fixing it to the table. The woman tries to help the man. Shortly after that the husband discovers that his wife is held captive in a secret room in the back of the workshop.

I would really appreciate some help with this movie.

Thank you.
