Join the Beyond Skinwalker Ranch team as they uncover a massive sinkhole and hidden tunnels at Mount Wilson that may lead to a buried UFO. In this shocking investigation, they also capture chilling footage of a shadowy figure in the very room that terrified billionaire Robert Bigelow. In an effort to gain a broader perspective and build larger data sets, the Skinwalker team adds two team members and takes the offensive by pursuing evidence of similar phenomena found at analogous sites around the country.
