The stone giants of Easter Island are some of the most recognizable statues on Earth, and some of the least understood. How were hundreds of these enormous figures built, and why? And what sent them toppling to the ground? Was Easter Island's cultural decline caused by natural disasters, overpopulation, or war? Join host Adam Mastrelli and a team of experts as they gather evidence on the island in an attempt to understand one of the most mysterious civilizations in the world. Then see how one statue carried away by treasure seekers may help researchers decode what really happened on Easter Island.

In November 2012, in the small town of Fregerslev, Denmark, a discovery was made at a construction site that stunned the archaeological world. Hundreds of exquisitely decorated pieces from a thousand-year-old horse's bridle. Forensic analysis pointed to this being the resting place of an eminent Viking warrior during a crucial point in history. Join the excavation as a team of scientists attempts to reveal the secrets of a tomb full of golden riches, a missing body, and evidence of the beginning of the end of the Viking Age.
