Ghost Hunters International follows the adventures of a new team of paranormal investigators as they apply their principles of scientific debunking to some of the most legendary haunted spots around the world. Like their U.S. counterpart, TAPS (The Atlantic Paranormal Society), Ghost Hunters International is a squad of real-life ghost-hunting experts - ordinary people who investigate and attempt to debunk claims of otherworldly activity. Comprised of veteran TAPS investigators Robb Demarest, Andy Andrews, Brian Harnois and Donna La Croix, along with Barry Fitzgerald (memorable from the Ghost Hunters' legendary investigations in Ireland) and newcomer Shannon Sylvia, the Ghost Hunters International crew is primed to uncover some of the most startling paranormal evidence yet!
The GHI team travels to Ireland to investigate Roe Valley Hospital, where the spirit of a long dead doctor is still said to be seen. Then, the team ferries onto Spike Island prison to seek out the infamous Banshee on Ireland's Alcatraz.
