Jim, an ardent Bigfoot believer, and long-suffering girlfriend Kelly head deep into Six Rivers National Forest in Northern California, video camera in tow, to the site of the Patterson-Gimlin film, a1967 fragment of footage purporting to show Sasquatch. They first stop in Willow Creek, the Bigfoot capital of the world, where various locals talk to Jim's camera, warning them to keep out of the woods. That night Jim and Kelly are awakened by mysterious sounds that might be Bigfoot but might also be locals messing with them. Either way, they're not welcome here and so Jim and Kelly decide to leave at dawn if it's not already too late.
