The team arrives in Austria for the first time to investigate the eerie Moosham and Schloss Porchia Castles. First up, is the Moosham Castle, which was built in the 13th century by the Mooshimmer. Moosham Castle was allegedly a torture site during history's bloodiest witch trial. When the archbishop made accusations of witchcraft against certain women it was off with their— well, yeah, you know where we're headed (no pun intended!).

Still high off the success of the investigation at the Moosham Castle, the team takes on the Schloss Porcia. The Porcia Castle was built in 1533 by the Salamanca dynasty and was purchased in the 1950s by the government to be used for a variety of purposes. The mayor, police department and caretaker have all had personal experiences with paranormals on the property. The most chilling legend surrounds Katharina, the last of the Salamanca family, who is said to have killed a worker with a wooden shoe. And they say good help is hard to find. To date, people claim to see Katharina roaming the castle's halls at night.
