Thousands of years ago, the survivors of a clash between two ancient tribes land on the icy shores of Antarctica. It seems death is near, but mercifully, they find a lush, warm valley with a unique microclimate where they could live and prosper. The problem is, something is already living in this valley: a colony of giant reptiles that had once dominated Earth.
Having nowhere to go, the newcomers are determined to stand their ground and fight until victory... or death. Who will claim the only warm oasis in the frozen desert?
