Secrets of the Unknown daringly showcases the bizarre, the terrifying, and the unmistakably real. First, Bigfoot brings together eyewitnesses who relate their encounters with the legendary and mysterious 800-pound creature. Then, Witches explores the long and clandestine history of this misunderstood group of people and provides a close look at the black art with factual information presented by practitioners.
