Hannibal, one of history's most famous generals, achieved what the Romans thought to be impossible. With a vast army of 30,000 troops, 15,000 horses, and 37 war elephants, he crossed the mighty Alps in only 16 days to launch an attack on Rome from the north. For more than 2,000 years, nobody has been able to prove which of the four possible routes Hannibal took across the Alps, and no physical evidence of Hannibal's army has ever been found…until now. In Secrets of the Dead: Hannibal in the Alps, a team of experts – explorers, archaeologists, and scientists – combine state-of-the-art technology, ancient texts, and a recreation of the route itself to prove conclusively where Hannibal's army made it across the Alps – and exactly how and where he did it.

The only one of the seven wonders of the world still standing, the Great Pyramid of Khufu has fascinated people for centuries. Tracing the origin of the legends of secret chambers hidden in the heart of the pyramid, Secrets of the Dead will show what lies within, solving a 4,500-year-old mystery, by following the first scientific mission in 30 years to be authorized by the Egyptian government to examine the pyramids of Egypt.

Passionate about ancient history, the global team of Scan Pyramids consists of particle physicists, experts in innovation and 3D technologies, and engineers in thermal imaging from Egypt, France, Japan, and Canada. For more than two years, they explored every corner of the pyramid, using non-invasive technologies including infrared cameras, 3D scanners and cosmological particle detectors located inside and outside the monument. Their search detected unknown cavities in the Great Pyramid of Khufu for the first time since the Middle Ages. Witness Scan Pyramid's adventures and successes in this extraordinary scientific and historical journey through time and space that led to this historic discovery.

Join a team of archaeologists, scientists, and historians as they reveal the little-known history of America's Spanish colonists who settled in Florida in 1565, long before Jamestown or Plymouth were founded. Narrated by actor Jimmy Smits.
