The first days in Portlock have left the team members distinctly 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, while the creature leaves a stern warning.

The team continues to make shocking discoveries in eerie Portlock, including a mysterious obelisk in the forest. They’re joined by a psychic medium who wants to build a spiritual bridge to Nantinaq but panics when she senses a dark and deadly 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. And 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 near the Spooky Tree.

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.

The team is unnerved by evidence that Nantinaq may be lurking in the water. They head back to No-Man's Land with night-vision goggles to spy on the creature, but things get out of control fast when they spot an inexplicable blaze in the woods.

Paranormal investigators arrive in Portlock to perform a powerful cleansing ceremony to rid the village of its dark, demonic energy. Calm seems to prevail as the team's 40-day mission draws to a close, but has Nantinaq truly been banished from Portlock?
