The group heads to West Virginia for a two-part investigation at one of the most haunted buildings in America: the Trans-Allegheny Lunatic Asylum, a sprawling abandoned psychiatric hospital with a tragic history and countless reports of paranormal activity.

Josh, Phil, and Heather continue their investigation into the Trans-Allegheny Lunatic Asylum, where thousands died after disturbing medical procedures. It's said their ghosts roam its now-abandoned halls.

Phil and Heather investigate the world's most iconic cryptid: the elusive Loch Ness Monster. Joined by actor and monster hunter Rhys Darby, they journey deep into the Scottish wilds to explore compelling new evidence beneath Loch Ness' murky waters.

The team heads south to a haunted city: Savannah, Georgia; they investigate horrifying reports of violent paranormal activity inside one of its oldest buildings, the Sorrel-Weed House, where a family died in shocking circumstances.

Heather and Phil continue their investigation of Savannah's haunted past.

The team goes to England to explore Chillingham, Britain's most haunted castle; thousands died in brutal battles on its grounds or by horrifying tortures in its dungeons; now, hostile spirits are said to roam the medieval building, seeking vengeance.

The team investigates reports of what some believe is a government conspiracy: the Dogman; this half-wolf, half-man monster is said to stalk the Michigan wilderness, and some even say this creature was created by the US military.
