简介：After the American Army shot down a UFO in 1947, generations of elite commandos were secretly trained to deal with the aliens' feared return. However, the extra-terrestrials never came back and the elite force was disbanded. Sixty-six years after the Roswell crash, the aliens are invading Earth and only the over-the-hill retired commandos can stop them.
