Looking for the title of a courtroom drama (knowing some plot details)

Hi! I would really like to find this movie which I think it's from the 80s or 90s.

What I remember is (of course, SPOILERS ahead): * 1. it's courtroom drama * 2. the defendant is accused of self-defense murder (she stabbed a guy who was raping her in her apartment) * 3. while the crime was happening, her lover (a married man) was outside the window on the fire escape ladder and watched the whole scene * 4. in reality, she planned the whole thing (she usually likes rough sex and the supposed "raper" was one of her lovers and it was common for them to do it while she was asking him to stop - there was loud music in the room and a recording of her screams could be interpreted both ways) * 5. her motive was to make her relationship with the married man public and destroy his marriage * 6. her and the married man were in a relationship when they were younger and climbed together a mountain which - I think - had "devil" in its name (he frequently has flashbacks of this during the trial and this helps him understand the truth at the end) * 7 she gets away with it because he understands everything too late and cannot be involved in another trial for the same crime

Sorry, but I don't remember any of the actors. I thought the married man could be Harrison Ford, but I think I'm getting mixed up with Presumed Innocent.

Thanks to anyone who has a better memory that I do!!!
