A science fiction, found footage audiodrama. Park and Blake are tasked with guiding two corporate employees through a cave system. They trust themselves. They trust the ground beneath them. They don't trust the strange machines their clients bring along. A few days ago, Andy found a box of cassettes. On them are the final recordings of a failed caving expedition. She recruits her best friend, Jess, to listen to them with her. But as the tapes start, they hear some familiar voices. Their own voices.
