After the completion of his film, CHEST, in 2022, filmmaker Aaron Irons set out to document the real legends and stories that were the basis for the plot of his film. After receiving a cryptic email with coordinates to a mysterious legendary cave in the Jeffrey's Hell area of the Citico Wilderness in East Tennessee, Aaron set out to find the cave. He never returned and his whereabouts are still unknown. In 2023 an anonymous documentary film crew came across Aaron's story and set out to find answers. What they found was a deeper conspiracy and something much more sinister than a simple missing person's case gone cold. Friends and fellow cast and crew members of CHEST come back together to talk about what they do and do not know about Aaron's disappearance and just why is the FBI involved in a missing hiker case?
