"Proof! There are giant creatures living at the edge of our civilization." Actor Peter Graves (Airplane!) hosts and narrates this 1976 documentary campfest about Bigfoot, the Loch Ness Monster and other mysterious phenomena. Seventies-era technology is used to scrutinize eyewitness accounts, footprints, audio and video?and prove that these elusive creatures are real. "The most startling film you may ever see" also examines psychics, hypnotism and the history of the yeti in ancient cultures. THE MYSTERIOUS MONSTERS asks the crucial question, "If fingerprint evidence can be used to hang someone, why can't footprint evidence be used to prove the existence of someone?"
