The Ghost Hunters International team visits Bodelwyddan Castle in Denbighshire, Wales. Shrouded in mystery and housing unidentified bones in its walls, the only thing certain about this castle is the presence of unexplained shadows and drifting figures through its long corridors.

The GHI team investigates the Nottingham Road Hotel that is haunted by a dead prostitute, and Cape Town Castle.

The first ever to investigate this ominous site, the team explores Slovenian national monument, the Predjama Castle. The team then travels to another castle with a far more gruesome tale, The Bathory Ruins at Cachtice Castle in Slovakia.
