What happens if it actually works?
Everything you think you know about modern science is about to unravel.
While conducting experiments in a garage, two brilliant engineers who lead double lives accidentally discover that their project enables them to travel back in time. Each man's curiosity leads to experiments without the other's knowledge, some with serious consequences. In an "ingenious blend of sci-fi and mystery" (Steven Read, "Philadelphia Inquirer"), viewers are challenged to solve the puzzle that is PRIMER.
