Sasquatch. The Loch Ness Monster. The Abominable Snowman. These are creatures of myth and legend. But now, a new mystery known as Hogzilla has emerged from the swamps of southern Georgia. But this legend is different because one man claims he killed the creature, a purported 1,000 pound feral hog the size of a pick-up truck. He knows exactly where it is buried and his conquest is even celebrated in a town-wide festival. National Geographic goes on a forensic investigation into this mysterious creature and find out the truth behind the legend of Hogzilla.
