Brothers Jim and Bill Vieira discover a previously unknown hidden chamber where they believe a giant skeleton may be buried.                           

The Vieira brothers travel to the Ozarks and make two possibly game-changing discoveries.                                                              

The Vieira brothers track promising leads on the Goshen Mystery Tunnel site, and on a giant skeleton found in 1849.                                    

When the Vieira brothers head west to explore an island shrouded in mystery, they uncover compelling evidence of giants, but their investigation takes a dark turn.

Chasing accounts of giant skeleton discoveries, Jim and Bill Vieira follow in the footsteps of Abraham Lincoln, who was fascinated by tales and legends of ancient colossi. Along the way, the brothers encounter a witness to a potentially explosive find in Ohio and descend into a dangerous but promising cave in Tennessee.

Along with a team of archaeologists, the Vieira brothers discover new evidence about the Goshen Mystery Tunnel, and Jim investigates a giant account unlike anything he has seen before.

Real monsters are behind our greatest legends. Stories of giants and beasts permeate our past and fascinate us in the present. From the Bible's Goliath to the Cyclops of Greek mythology, our colossal adversaries inspire tantalizing tales of terror. Now, new evidence suggests that many of these mythical creatures may have been anything but made up. Could the real labyrinth of a man-bull named the Minotaur have been discovered? Do fossils prove Cyclops legends are true? Could a monster named Grendel from the famous tale of Beowulf actually have stalked a banquet hall in Denmark? New evidence suggests many of our giants and beasts were real - but in ways you've surely never imagined.

Many explorers throughout the centuries, including the great Ferdinand Magellan, visited the region in South America now known as Patagonia and reported sighting giants. From these accounts we get the name Patagonia --Land of the Big Feet.
