First off, it must be said that this movie is one of the most honest and compelling stories told in movie I have ever seen. The problem is, you have to be completely ok with seeing the normal, average, everyday life of a couple of tech geek engineers (the real thing, not the Hollow-wood version) to get both the story context and plot delivery. Because of that, the audience for this film is a thin one.

But if you can handle it, this movie will completely blow your mind. Welcome to what seems like actual footage of someones real struggles with being a workplace engineer trying to turn entrepeneur in their garage. A couple of smart but very believable engineers are just trying to hit the common-mans paydirt of figuring out something that will make them money as a nice new discovery- they just want to make a better refridgeration unit for your home icebox. Not sexy science by any means. The setting is low tech on the computers, and high tech on the physics and chemistry. But in the common-sense approach taken by our two main characters to work through generating a low powered cooling system, they stumble on something that begins with a sustainable energy source and ends up as a mechanism allowing you to pass a human through time, precisely one day into the past.

If you are a science based professional, you must watch this movie to see how this story is taken from common science to science fiction (or is it?). The smartest and most clever thinking in a film for a very long time.

If you think this sounds stupid to you, and you do not have a practical working basis for science (and therefor good science fiction), then don't get this film. No engineer should pass up this film.

Of course, as you can guess, there is tension and need for resolution. In this movie, the plot moves from discovery of this new technology to a reality and morality check with Abe and Aaron (our main characters) trying to figure out.

I won't give away more, but if you are looking for brain teasing then you have hit the motherlode with this film. In the end, true geeks will be rewatching certain scenes of this movie over and over, trying to convince themselves of what happened. The film smartly captures emotion and dialog in a peircing reality of human ambition. You become as wrapped up in the story as the two scientists who are trying to outsmart one another. The results are fabulous, if you can stand the detail and tech talk.

Flat out the A movie for true geeks, but a D movie for people who want to see something predictable and simple. For my money, everyone (even those who hate geeks) should see this movie-- just so they can watch some stark reality filming done masterfully.

I personally give this film an A-, but your mileage may vary extremely different depending on your personality, interests and educational background in science.
