This film is a combination of science fiction and good old-fashioned film noir, complete with mystery and intrigue. It is a little slow to start but once you're hooked, you really do want more.
Without giving too much of the plot away, the story is about time-travelers and revolves around three main characters, with a fourth character who is integral to the story but doesn't get as much screen time as the other three. The characters are a female 1950s pulp detective novelist, the mysterious man one presumes to be her paramour, and a modern day woman. The fourth character is an intriguing African American woman whose presence is known throughout the movie but she isn't seen except at the beginning and the end. Essentially, these folks are time travelers and it is sort of through the modern woman's eyes that the viewer sees the events unfold. We know as much as she knows and we find out what she uncovers as the movie progresses.
This is a movie that is really hard to pin down without giving away all of the essential plot points. That's what makes it an interesting piece to watch. One suspects it was a low-budget film but even so, there's some really nice artistic flourishes thrown in and the acting is so good, you forget that it probably didn't cost too much to shoot this flick. I like how the film handles the concept of time travel without any flashy special effects. It's simple and just plain cool once you think about it. One caveat though, for those expecting a lesbian film, this is not really it. There is some lesbian subtext but for the most part heterosexuality is the maintext. I thought this was a lesbian movie about lesbians but that wasn't really the case. It's ok though because the movie is so interesting and well done. As long as you're not expecting a lesbian movie, you won't be disappointed.
You should watch this movie just because it will give you something to think about and discuss with anyone who watches it with you.
