Expedición: Pie Grande

The team returns to the Olympic Peninsula with a plan to lure out a Bigfoot by releasing primate pheromones. But after Ronny and Mireya see something watching them, and Russell is blindsided, it becomes clear -- the hunters are now the hunted.

Russell tracks a massive creature to a box river canyon but finds he can't escape a shadowy figure on the prowl. Bryce discovers Bigfoot is lured in by whistling, while Ronny and Mireya realize something is watching them from across their base camp.

A mysterious shadow figure gets too close for Ronny and Mireya's comfort. Russell tracks a large creature along a well-used game trail but quickly realizes he's being stalked in return. Bryce makes an unsettling discovery at the bottom of a lake.

The team ascends massive pine trees in search of evidence from above. Bryce uncovers government secrets that may include underground bunkers. A 3D image specialist discovers possible man-made structures deep in the forest and captures a ghostly image.

Ronny, Mireya and Bryce search for a top-secret government research facility hidden beneath the forest, and a witness comes forward with his up-close encounter with Bigfoot. Meanwhile, Russell is unnerved by a gruesome discovery.

The investigation reaches a fever pitch as the team uncovers a potential Bigfoot kill zone directly above Lake Fear. Thrilled by their findings, they launch a squadron of patrol drones to sweep the area for definitive proof of the existence of Sasquatch.

The team has a truly shocking sighting, only to see their best lead yet lead slip through their fingers. But a groundbreaking tip leads Bryce to wrap up their expedition in Washington State and relocate to a new Bigfoot hot spot.

At their new base camp in California, the team records a howl unlike anything they've heard before. Later, Bryce learns of a potential Bigfoot coverup by the US government. And Russell, Ronny and Mireya come face-to-face with danger while on a night hunt.

Russell finds fresh clues along an abandoned railroad track, while Ronny and Mireya experience a hotbed of unexplained sounds deep in the forest. Bryce learns chilling new information about the history of Bigfoot in Northern California.

Russell uses an unlikely ally to pursue a strange predator, while Bryce investigates the team's recent run-ins with mysterious floating orbs. After an invasion of their base camp, Ronny and Mireya use modern means to track a creature in the woods.

Using new tracking technology, Russell gets closer to his quarry than ever before. Bryce learns that Bigfoot may have psychic powers, leading Ronny to use an unusual technique to draw one out. And Mireya is startled by strange lights in the night.

A visibly shaken Ronny and Mireya want answers about the unexplained activity they encountered the night before, while Bryce is baffled by strange lights on the security camera. The expedition takes a frightening turn when a team member goes missing.

The team pulls out all the stops to corner Bigfoot. Mireya travels on horseback to find evidence, while Ronny recruits a psychic specialist to hone in on the creature. Finally, Russell catches sight of what could be real proof of Bigfoot.

When Russell films a shocking piece of video evidence, the whole team assembles to follow the trail. After a grueling journey through treacherous terrain, their search culminates in a monumental discovery.

After an epic investigation in Washington State and Northern California, the team regroups to discuss their adventures and analyze evidence collected from the field. Shocking new discoveries lead the team to a new target for their next expedition.
