It is probably a late 80's or 90's crappy (erotic?) thriller movie.
In the scene I remember, a woman seduces a man, gets on top of him on the bed, handcuffs his hands to the bed posts (each hand to a different bed post) and leaves the room.
If I remember correctly the woman plans to turn the man into the police (he might be suspected of a murder). The man uses his legs to turn the top of the bed post to unscrew it and then escapes.
I vaguely remember there might be some double/doppelganger/parallel universe motif in the movie (a female double) but I'm really not sure about that.
