Contact

It's the age-old question that has daunted scientists, government officials, explorers, religious leaders and populations around the world for centuries - have aliens made contact with Earth? While more than half the U.S. population believes they have, most sightings and theories still lack the evidential proof to silence the naysayers. In Contact, six highly trained investigators seek to find the answers we've all been searching for. Using groundbreaking CIA developed software, military special operations investigative techniques and boots-on-the-ground journalism to track down leads around the world, Contact is the first ever global investigation to determine whether or not aliens have made contact here on Earth.
