Primer

[Zion]

If you always want what you can't have, what do you want when you can have anything?

Primer is a psychological sci-fi thriller about a group of four tech entrepreneurs. Toiling away in a garage, the quartet have successfully created error-checking systems for their clients. But their recent work seems to have created an unexpected and seemingly impossible side-effect. Suddenly, two members of the group realize they are in possession of a device that can double, or perhaps even quadruple, the space-time continuum of anything that enters it. What at first seems like a windfall of astronomical proportions eventually proves to be much more than they bargained for, as the duo attempt to manipulate time to their financial and emotional benefit.

couldn't too much summarize myself, but it's worth the watch.
