Overview

What begins as a rescue mission quickly turns into a harrowing fight for survival. When renowned cryptozoologist John Hadley disappears while investigating a series of caves deep in the Sierra Nevada mountains, his daughter, Emily, is thrust into a desperate search to find him. Teaming up with Evan Morgan, a local deputy and former flame, Emily uncovers disturbing clues that suggest her father was onto something far more dangerous than she ever imagined. As they push deeper into the wilderness, they soon realize they are not alone. Something ancient and powerful lurks in the caves-something that has been watching, hunting, and waiting. They also discover that John's obsession with Bigfoot was not just the stuff of myth. The creature is real. And it's deadly.
