Sequel to the popular 2006 horror remake. An isolated desert research camp has been mysteriously abandoned, and now it's up to an elite unit of soldiers to uncover the truth about the scientists who vanished without a trace. Their attention is soon diverted by a distress signal emitting from a distant mountain range, the squadron quickly regroups and sets out to investigate. Unbeknownst to the soldiers, however, is the fact that these are the very same hills where the Carter family recently fell prey to a flesh-eating pack of hideously deformed mutants. As the ranks of the cavalry unit steadily begin to dwindle, it soon becomes obvious that their guns provide little defense from an evil driven by hunger to commit the ultimate crime against humanity.
