From the terrifying bat-winged “Jersey Devil” to the deadly “Night Marchers” of Hawaii, Cliff is determined to uncover the truth behind these nightmarish myths and legends. That means using all his skills to hike, swim, and even crawl his way into places most people wouldn’t dare to go. Along the way, scientists, shamans, historians, and witnesses all provide clues that shed light on dark secrets that often defy explanation. He consults with local guides to help plan his route, but after that, Cliff is on his own, venturing solo, deep into one extreme landscape after the other, to haunting places where the wilderness and the paranormal intersect.
