What if I told you that for two thousand years, many of the world's most powerful men have pursued an ancient artifact they believed would bring them unparalleled power? It's the lance that allegedly pierced Jesus' side while he was nailed to the cross. Known as the Spear of Destiny, it passed through the hands of leaders like Napoleon and Adolf Hitler, and today there are a number of shadowy institutions around the world that are still chasing the Spear. Yet the question remains: does the Spear really exist, or has it been lost forever? Decoded pursues the truth about the Spear across two continents, and tries to solve this centuries-old mystery.

Government authorities say it's "not if... but when"...a moment in the future when, just as it has in the past, some catastrophe sparks mass destruction, leaving humans challenged to find shelter, heat, food, water and defense. If that happens, would you know what to do? Survival expert Rudy Reyes journeys through abandoned buildings showing us some surprising survival techniques, including making fire from steel wool, finding safe houses and creating shortwave radio transmissions.

The life story of Nostradamus unfolds in medieval Europe at the time of the Great Plague and the Inquisition. He lived in an age of superstition and magic and believed that he could foretell the future. For this he was labeled both a prophet and a heretic, and his cryptic journals continue to inspire controversy just as they did in the 16th century. In this 2-hour examination of his life, we visit his birthplace in France and trace his career as doctor, astrologer, father, and seer.

The Roman Emperor Nero, renowned for playing the fiddle whilst Rome burned, was infamous for cruelty, incest and murder.

As a child, Hannibal from Carthage, modern-day Tunisia, was forced by his father to make a blood to destroy the Romans. His reputation as one of history's cruelest generals was earned as he ruthlessly slaughtered women and children along with tens of thousands of his own and enemy soldiers in the pursuit of defeating Rome. While he won several major battles, he curiously gave up before marching into Rome.

The infamous Queen of Egypt, known for her legendary powers of seduction, would stop at nothing, even murdering her entire family, to get her own way. Driven by power and ambition, her life was dominated by a heady cocktail of sex and murder.

This young Roman emperor had a fearsome reputation as a sadist, a murderer...and a raving lunatic.

The ruler whose ego was as big as his empire declares himself dictator of Rome for life--turning his allies to enemies in the process.

At this very moment, celestial forces prowl the Universe and threaten man's very existence. They're asteroids and comets--and they've left their imprint on planet Earth, literally. Initially, they helped build planets through violent collisions. During this fiery bombardment period, they may have even seeded Earth with water and the building blocks for life. Since the turbulent formation of the solar system, these space rocks have continued to impact earth. Some have been so violent that they've led to mass extinctions events, including one that wiped out the dinosaur. What's more, radical new theories suggest that asteroid and comet dust harbor deadly viruses that may have triggered some of our worst pandemics. The possibility of future cosmic collisions remains a legitimate threat. Yet, despite their dangers, asteroids and comets may hold vital natural resources, which could actually preserve mankind.

Miracle technology could allow people to transmit their brainwaves and speak to each other mind-to-mind. Scientists are working to create computers that read thoughts to find terrorists, and machines to scan our minds like thumbprints--causing some to wonder if "thought theft" could become the crime of the future.
