We've spent decades preparing for first contact. Many people expected extra-terrestrials to find us, but we found them first. When an alien race is discovered on a distant planet, special measures are put in place to prevent them posing any future threat to Earth. A crew of highly-trained specialists is deployed to Terra 1 to neutralise extra-terrestrial military installations. They went to safeguard our future, but when nothing on Terra 1 is what it seems, can they even make it home alive?
