Sezon 1

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

The Viera 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.
