When Gavin Gore and his three friends, Hobie, Maynard, and Sophie go for a hike up to Deer Cliff Falls, they discover some suspicious footprints and scat that they assume can only be from one source—Bigfoot. They quickly decide to alert police and the media of the find and start a small sensation in their town. But even as Gavin and his friends seek to prove the validity of their own claims, their dimwitted neighbors Zerk (Justin Long) and Shirts are on a quest of their own to save their precious Pontiac Firebird from being repossessed by the bank. Zerk comes up with the idea that they should sell plaster casts made from the Bigfoot tracks online. A self proclaimed Bigfoot expert comes to town to verify if the tracks are really from Bigfoot. Suddenly, the profitability of their operation is in jeopardy based on the diagnosis of Dr. Artimus Snodgrass, Sasquatch expert.
