Follows a group of amateur paranormal investigators creating a documentary about four teens missing since 2012, a case that remains unsolved despite recovered camera footage from the day of their disappearance.
The investigation leads them to the teensβ last known whereabouts: a cave deep in the Malibu mountains, where they set up camp. Attempting to communicate with the spirits within, the investigators bring forth an ancient demon intent on guarding the land and enacting the same gruesome fate those four teens met ten years ago.
