A UFO descends over the Rocky Mountains in North America, and Sky One closes in for the kill. But Foster and a squad of Mobiles are closing on the area too, and with the opportunity to capture an Alien alive, the order is given to let it land. Settling beside a cliff, the UFO is hemmed in but when an operative sees a hatch open and moves forward to investigate, it self-destructs. Foster does not believe the Alien would allow himself to be destroyed so easily, and sure enough they find a old mine-working entrance behind the wreckage. Foster goes in alone, and finds an Alien device.
