The team return to the Olympic Peninsula with a plan to lure out a Bigfoot by releasing primate pheromones. After Ronny and Mireya see something watching them, and Russell is blindsided, it becomes clear that 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; Ronny and Mireya realise 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 realises he's being stalked in return; Bryce makes an unsettling discovery at the bottom of a lake.

The team ascend huge pine trees in search of evidence from above. A 3D scan discovers possible man-made structures deep in the forest and a ghostly image.

The team look for a top-secret government research facility hidden beneath the forest and, in doing so, encounter Bigfoot.

The team uncover a potential Bigfoot kill zone directly above Lake Fear. Thrilled by their findings, they launch a squadron of patrol drones to sweep the area.
