Soldiers stop at a
New Mexico outpost in order to deliver equipment to a group of atomic scientists. When they arrive at the isolated research camp, however, they find it is mysteriously deserted. After spotting a distress signal in a distant mountain range, the team decides to embark on a search and rescue mission into the hills in order to locate the missing scientists. Little do they know that these are the very hills that the ill-fated Carter family once visited, and that a tribe of cannibalistic mutants lies in wait. And this time, there is an even larger force of evil at work than the last time: the worst of the worst - the family patriarch Papa Hades - plans to keep the women as breeders in order to ensure the survival of the mutant clan. Thus, the inexperienced group of soldiers must learn to band together against a foe that is intent on their very destruction. This movie is much different from the first, it shows the mutants mines, and where they lead. They seem smarter in this movie. They have holes in the ground in which they surprise anyone they wish to kill/eat. Much like the first movie, one of the mutants helps the humans. In the end, it shows as in the first movie that there will be another to the franchise. As in the final moments of the movie it shows the surviviors on a thermo imaging screen on a laptop as shown in the beginning of the movie. It shows that a mutant is watching them escape, who then closes the laptop in frustration.
