Season 4 kicks off with those classic little green men that the paranormal community can't get enough of: Leprechauns! We trace the origins of Leprechauns up to the modern day, from the saga of Fergus mac Léti to Warwick Davis. But is there any truth to the tales of the gold-loving fae folk? And if Shibble was going to write a Leprechaun movie, what would it be like? Only one way to find out: tune in! Just remember, don't get spooked!
