Comments: The film begins with a figure emerging from what looks like a mirror and murders a woman. The masked perpetrator takes off her costume, dresses as the woman, and returns to bed with "her" husband. The murderer looks, of course, just like her victim. Jump ahead a few years and a group who formed a small IT company are renting the house. They discover a mirror in a walled-off attic space. They find that it allows travel between alternate universes!
This film is intriguing. It provides a decent character study of the main characters as they deal with the mirror.
