This program is a modern day quest to find the truth behind one of exploration's greatest mysteries: what happened to famed adventurer Col. Percy Fawcett, who went looking for a city of gold -- the Lost City of "Z" -- in the Amazon in 1925 and disappeared in the jungles of Brazil forever? New archaeological digs, the science behind the discovery of "newly found" jungle cities and clues collected over the years reveal the fate of Fawcett. The program unravels the truth of what really happened to Fawcett and shares surprising finds that are causing experts to re-think the image of a pristine uninhabited Amazon rainforest: a place that before Columbus, may have had large populations living in sophisticated towns and cities. Fawcett may have actually discovered these ruins fueling his fervor to find the city of gold. Cutting between stylized dramatic Fawcett recreations, old films and archival photos, interviews with family members of Fawcett, jungle villagers and scientists at ancient Indian archaeological sites -- the truth about Fawcett and new understandings of life in pre-Columbian America emerge. Trekking along the paths that Fawcett followed, the search for clues ends at a Xinguano-Kuikuro village in the heart of the Mato Grosso: where a new archaeological discovery may reveal the true location of the Lost City of Z.

The royal tomb of Pharaoh Psusennes I is one of the most spectacular of all the ancient Egyptian treasures - even more remarkable than that of Tutankhamen. So why hasn't the world heard about it? What mysteries does it contain? And what does it reveal about ancient Egypt? The tomb was discovered filled with lavish jewels and treasure almost by accident in 1939 by the French archaeologist Pierre Montet while he was excavating in northern Egypt..The royal burial chamber came as a complete surprise no Egyptologist had anticipated a tomb of such grandeur in this area. Unfortunately, the tomb was found on the eve of World War II in Europe and attracted little attention. One of the most startling discoveries inside the tomb was the sarcophagus in which the body was held: It was made of silver with exquisite detail and craftsmanship. No other silver sarcophagus has ever been found and it is now recognized by many Egyptologists as one of the most exquisite artifacts of ancient Egypt ever to be found. The elaborate tribute within the tomb suggested it was the burial site of someone very important but as archaeologists, using the hieroglyphs inside the tomb, pieced together the identity of the pharaoh, they were left to wonder who Psuesennes I was and why he received such grand treatment. The investigation reveals political intrigue, a lost city and a leader who united a country in turmoil and became the Silver Pharaoh.

It made Tutankhamen the most famous name in ancient Egyptian history. But the real story has become shrouded in myth -- with many mysteries around the tomb unsolved to this day. This two-hour special combines the latest evidence from a team of archaeologists, anatomists, geologists and Egyptologists to build the ultimate picture of Tutankhamen. Blending 3D graphics, stylized reconstruction and action-adventure forensic investigation, the programs take a 21st-century approach to ancient history, following new scientific research and presenting fresh insights into how Tutankhamen was buried, why his tomb was the only one to remain intact and the enduring enigma around how he died.

What happened here 49,000 years ago will take viewers on a much bigger journey - from El Sidron to the other end of the Iberian Peninsula, where scientists are excavating beneath the seas off Gibraltar in search of Neanderthal sites.

DEATH ON THE RAILROAD is a classic story involving foul play, cover ups, a murder mystery and a voyage of discovery to understand what happened to a group of Irish men who came to America for a better life but found only misery. In 1832, railroad contractor, Philip Duffy, hired 57 Irish immigrants to lay railroad tracks in West Chester, Pennsylvania. But, less than two months after their arrival, all 57 were dead.

In 2003, twin brothers discovered a secret file among their grandfather's papers that led them to investigate the deaths of these men and find the location of their final resting place in a valley now known as Duffy's Cut. Using the latest forensic and scientific investigative techniques, DNA, forensic analysis, facial reconstruction and historical detective work in Ireland and the USA, modern detectives and experts will unravel this extraordinary story.
