Animal tracker Ivan Marx opens by mentioning the film is the culmination of 10 years of research.

He says that the Eskimos called the creature "bushman," the Colville Indians "Sasquatch," and the Hoopa "Om-mah," but is most commonly known as Bigfoot.

Marx's brother-in-law takes him to the land of petrified wood, showing him rock carvings of creatures with big hands and feet.

He visits the Oh-mah bigfoot redwood statue in northern California and the Oregon coast, continuing to search.

Marx shows footage of an injured squirrel, goats eating dirt, and glaciers melting.

Marx travels above the Arctic Circle, showing footage of the Northern lights while relating Bigfoot tales.

Later in the evening, he films what he describes "the shining eyes" of the creature, but when dawn comes, he says Bigfoot disappeared behind a rainbow.

Marx shows footage of salmon spawning, geese migrating, caribou, and Alaska moose defending their territory.
