The team investigates England's Chillingham Castle.

The Abbey at Lucedio, Italy and the Nanteos Mansion in Wales are investigated.

The GHI team arrives at the Ragged School, formerly an orphanage and currently abandoned. The structure shares a basement connection with a shop called Camera Obscura, whose employees no longer venture into the basement because of all their experiences.

The team makes its way to Ireland, to check out Wicklow Gaol, a prison constructed in 1702 that once housed some 780 prisoners during the Great Famine. It's now a museum, but reports have been made of people being pushed or touched by unseen forces, seeing blood on the floor, and witnessing strange shadows and mists.

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.

This week, GHI investigates the Czech Republic's Castle Houska, a structure supposedly built to keep something in. Legend has it that the castle, dating back to the 13th century, was built over the Gates of Hell and meant to keep evil spirits from escaping into the world. Needless to say, the team is champing at the bit to get a crack at this gothic fortress.

The team goes to Trinidad to probe claims concerning the ghost of a cocoa plantation owner in the Season 3 premiere.

A former leper colony is probed on Trinidad's Chacachacare Island; the ghosts of four murdered workers are sought at a meat packing plant in Argentina.

The team heads to Barry's homeland of Ireland to investigate two local infamous cases. The first is at Roe Valley Hospital, a site that began as a workhouse - a facility where the homeless were forced to perform grueling labor - until it was transformed into a hospital by Dr. Robinson, a woman who is said to haunt the grounds today.
