Nearly every society and culture has stories of "monsters", beasts that are said to populate the remote regions. Some are familiar, like Bigfoot and the Loch Ness Monster. Others, like mermaids, have been categorically dismissed whilst others have been found! We now know that there are squid that reach lengths of 100 feet or more. The Komodo Dragon has deadly saliva, a nasty disposition and a bright orange tongue. Every time we move to dismiss a tale of some extraordinary beast, the stories of these unlikely leviathans should come to mind. Featuring controversial footage of legendary creatures and up-to-the-minute commentary from monster hunters, History's Mysteries examines the enduring tales of creatures like Bigfoot, the abominable snowman, and "Nessie", as well as others that are not as familiar. Every possible explanation is considered in an attempt to get to the bottom of these captivating legends.
