Im trying to picture a movie I recently watched, all I have to go on is 1 scene. The movie from memory was modern nothing pre-2000’s
A man and woman are having sex in I believe an apartment but it doesn’t belong to either of them, and from what I remember they are having an affir (potentially), during the sex scene, I think the room is booby trapped and an arrow I think is fired from within the walls and it kills the woman who is sitting/riding on top of the man. She ends up dying instantly but falls on to the guy unlucky for him he is handcuffed to the bed frame and can’t move and she remains leaning on the guy until the morning when the police arrive and the guys is trying to get her off of him as shes dead resting on top of him. The movie I believe focuses on a Serial Killer, and the police are finding scenes like this I think.
Some random thoughts which I don’t know for sure help but the arrow was not intened for her but the man and also the picture frame was the location from where the arrow comes from.
