Hi! I’m going to try to write as much as I can to explain the movie. It could have been a television episode or a short film. A woman or man (I think woman) is stuck in a big white space and cannot figure out where she is. She eventually learns she is stuck in a computer system where she is actually controlled by the real her and the computer her was created to become a personal assistant.
I really hope you can help me. I am not even sure which country this could have been from. Perhaps England or the USA.
