In New Zealand's Tongariro National Park, ancestral Māori mountain warriors, the legendary Kāhui Tupua, awaken, unleashing their unfathomable rage on army sergeant Taine McKenna.

As the ground splits and chaos erupts, McKenna undertakes a desperate evacuation mission, that is until he encounters a busload of equally desperate prison escapees. It's going to take everything McKenna has to get the civilians out alive. Yet the true horror lies deeper still in this heart-stopping tale where the land itself is the enemy and every step could be his last.
