This week, the GHI team conducts a pair of investigations. The first takes them to the Czech Republic, where a sprawling castle known as Cesky Krumlov has been the setting for numerous reports of supernatural phenomena. Constructed in the 13th century, the castle spans five courtyards, 43 buildings and 15 acres of land, making it one of the largest locations ever investigated by GHI.

Next, the GHI team moves on to Rathlin Island, off the coast of Northern Ireland. The target for the investigation is the island's Manor House, where caretaker Ksenia Zywczuk relates several stories of paranormal activity, including an exorcism that was performed in the house's Bedroom 6. We also hear from a witness who claims to have seen shapes moving around the back door of the dining room.
