All I can remember about this film is a bloke kidnaps a lady. He keeps her hostage in his cellar and watches her movements on a screen. When he goes down to the cellar he has to where a oxygen mask. He does operations on the woman to help save his wife's life. His wife can only communicate by blinking her eyes. A cop discovers the cellar door underneath a red couch. Can anyone tell me the name of this subtitled film? Thank you! It's driving me mad trying to think of it. :-)
