It is at least 15 yeart old film. I only remember this scene.
Two intruders break into the bedroom where man and woman were sleeping. I think they asked for the money. Then the husband is tied on the chair and the woman was tied on their bed. One of the inturders then raped the woman. The man watches his wife being raped. She tried to get rid of the raper, but could not do it. While she was raped, she looked at her husband with "that" look, you could asume she might enjoy it. I don't know what happend then, but I believe, that "look" was then reason for the arguing later. And maybe, don't know, maybe I mixed with another film, the man actually hired the intruders to rob the couple and the rape was not in a first plan.
I would be very happy if could anybody after this brief description can help me to find a movie title.
