I am looking for a film that was definitely shown on TV in early 90s. It is most likely an American film, because that's where most films on Russian TV at the time came from - unless they were Russian. I watched just the middle to the end of the film but I know the gist of the plot.
The main character is called Kara and in the beginning she is given an artifact of huge importance, which gives it's owner great power. She is given that by a friend (who is possibly in love with her), because her friend doesn't take the reponsibility of guarding this artifact too seriously. She loses / gives away the artifact and chaos and evil ensues.
And this bit I have seen. She and her friend are in a very dark space, which is like a funnel, no visibility, trying to crawl out to the top. She eventually manages it, her friend doesn't because he is weighed down by guilt for giving away the artifact.
Any clues on which film that might be? Thank you!
