Primer is the story of four men who have built a cottage industry of error-checking devices. But, they know that there is something more. There is some idea, some mechanism, some accidental side effect that is standing between them and a pure leap of innovation. And so, through trial and error they are building the devise that is missing most. The story of Primer is what happens when two of these men find the device and immediately realize that it is too valuable to market. The limit of their trust in each other is strained when they are faced with the question, "If you always want what you can't have, what do you want when you can have anything?"
The cast includes Shane Carruth, David Sullivan, Casey Gooden, Anand Upadhyaya, Carrie Crawford, Jay Butler and Samantha Thomson.
