This week the Ghost Hunters head to Fort Knox in Maine, then on to a family in North Carolina desperate for help with their paranormal problems. (P.S. This is a different Fort Knox- not the one with all the gold!) On to the Ferrell house in North Carolina, where recent increases in activity are really freaking out the owner, Janet Ferrell. A large black shadow has scared them in the past, but now there seems to be a ghost touching them and scaring their dog Harley to death!! Good thing Maddie is coming along to sort things out for her canine brethren.
