After bidding their loved ones farewell, the team arrives in Portlock by boat, and they immediately feel a sense of foreboding in the deserted fishing village.
The team are left unsettled as they discover evidence of Nantinaq’s hunting habits. Keith and Ash visit a historian, who fills them in on the town's bloody past.
The team discover a mysterious obelisk. Plus, a psychic joins the expedition to build a spiritual bridge to Nantinaq but panics when she senses a dark presence.
A nighttime excursion proves too terrifying for one team member, who flees Portlock the next day; replacing him is Guy, who is hellbent on getting answers; those answers might come from broadcasting Bigfoot vocal recordings to draw out Nantinaq.
A Bigfoot expert weighs the team's evidence and declares that Portlock is infested with the creatures, who he believes are violent interdimensional beings that derive energy from trees; later, the team stumbles upon a strange pit.
Keith fears Portlock is cursed when he learns the horrifying history of the mysterious coin; later, Ash regrets ignoring a warning not to venture into an abandoned mine, and Nantinaq stages a brutal attack on base camp in the middle of the night.
