Xtro 3: Watch the Skies

Colonel Guardino (Robert Culp) orders Lt. Martin Kirn (Sal Landi) and Lt. Fetterman (Andrew Divoff) to lead a group of marines to diffuse bombs on a remote island once used as a military practice target. When they arrive, they quickly discover that their superiors had ulterior motives and learn there is an alien (Xtro) on the loose. The men's mission and their fate become a matter of life and death as they pit themselves against the U.S. Military's cover-up and the vengeful alien monster Xtro. Watch the skies!
