Seeking closure over her parents' disappearance, Hanna joins a cave expedition, but finds more than she bargained for and awakens an ancient evil that was meant to stay buried.
What begins as a research trip with her professor and peers turns into a harrowing fight for survival when Hanna ventures deep into a remote cave system in Arizona, investigating the lost history of the Jivaros tribe, an ancient group infamous for their ritualistic decapitations. For Hanna, this journey was supposed to bring closure. She's spent her life haunted by the disappearance of her parents, searching for answers to the past. But as the expedition uncovers chilling evidence, something far older and more malevolent stirs in the darkness. Now, as the cave walls close in and her team is hunted one by one, Hanna begins to question whether she's uncovering history or awakening something that was never meant to be disturbed.
