The desperate survivors of a new Ice Age contend with sickness and infighting while attempting to contact the inhabitants of another outpost that's gone mysteriously silent in this claustrophobic thriller from writer/director Jeff Renfroe (ONE POINT O, CIVIC DUTY). Mother Nature has cast an icy spell over the Earth once again, driving the few remaining pockets of humanity deep underground. Under the leadership of Briggs (Laurence Fishburne), the inhabitants of Colony 7 have managed to endure against all odds. They've been maintaining close contact with Colony 5, the only other dominion known to have weathered the chilling winds above, when their radios go mysteriously silent. Determined to find out exactly what happened in Colony 5, Briggs ignores the objections of his vocal rival Mason (Bill Paxton), assembles a team, and ventures out to investigate. By the time Briggs and his crew discover exactly what they're dealing with at Colony 5, however, their own base may have already been compromised.
