Golau and some of the remaining men set out in pursuit and are joined by a pod of Neanderthal, who are seeking answers of their own. During the quest, the two species are forced to forget their differences and work together. Beyond the ice wall, the horrifying truth about the third species is finally uncovered and answers revealed that affect both hunter and Neanderthal alike - resulting in a bloody confrontation, the outcome of which has the potential to affect the very future of humanity.
