Ghost Mine S01E05 - Secret Passage

Patrick and Kristen say they find clues of the mine's connection to the secret society of the Free Masons; they believe there is a secret passage to another tunnel and set out to find it. They say "a mysterious presence" has sent "a threatening message" by disrupting the mine. During a campfire, Dingus' 9-year-old daughter goes missing after reporting a shadowy figure peeking through the trees. Stan tracks down a new mine shaft and quickly has his crew excavate it.
