Christopher Garetano delves into the legend of Mount Shasta in Northern California, where many people have mysteriously vanished throughout the years, never to be seen or heard from again. Decades of mystery have shrouded the mountain, creating a supernatural lore surrounding these disappearances - everything from an ancient civilization living deep beneath the ground to claims of paranormal activity. In search of answers throughout his investigation, Garetano meets with local enforcement and travels into the cavernous tunnels below Mount Shasta. After hearing accounts of beings from an ancient mystical civilization called Lemuria, and exploring the possibilities of alien abduction, Garetano decides to confront the mountain himself - hoping to get sucked into its mystique to find the answers he's looking for.
