A mining company sets off explosions near a remote Montana burg and gets a lot more than ore. As carnivorous prehistoric beasts emerge from the fissures looking for something to chow down on, it's up to the townspeople and local ranchers to grab their guns and corral the colossal critters in this action-packed sci-fi romp. Rib Hillis, Casey Fitzgerald, Vernon Wells, and Eric Roberts star. 89 min. Widescreen; Soundtrack: English.
