The Shroud of Turin. Is it the burial cloth of Jesus Christ? A work of art? Or the greatest prank ever pulled? The Vatican itself refuses to take an official position on its authenticity, and with limited access to the cloth for testing, there's seemingly no way for scientists to end the debate. Or is there? Join four experts as they explore four radically different theories, using groundbreaking research and archeological expertise. Their one goal: to decode a treasure that has been revered, rejected, and argued about for more than 600 years.

A ten-inch golden statue discovered in a cave near Bogota may be the key to the greatest treasure never found: El Dorado. For centuries, rumors of a "Lost City of Gold" attracted explorers and fortune hunters to the Colombian Andes in search of riches. Now, after 500 years of futility and bloodshed, investigators try to finish the job, using the found statue, a beautiful model of a golden raft, as their guide. See legend and fact collide as we apply forensic techniques and decipher ancient documents to uncover the truth behind the myth.
