Kearny and Donny MacGregor are famous hoaxers whose lineage can be traced to a long line of conmen and tricksters. Hours before the brothers perform a successful crop circle hoax, they are approached about creating an Earth light hoax for the mayor of Stony Creek, the Bigfoot capital of northern California.

After several successful Earth light hoaxes, a loose group of truth seekers forms, lead by Sheriff Nicki Stanford and local Bigfoot debunker Possum, and the chase is on.
