On October 20, 1967, Roger Patterson captured 60 seconds of film showing a creature walking through the Northern California woods—footage that became the most analyzed and debated in history. Fifty-seven years later, a reel of 16mm film discovered in a safe changes everything, revealing the untold story behind the world's greatest mystery, told for the first time by Patterson's own son and the people who were there.
