Man uses plants to feed, heal and clothe himself, to build his world and even to alter how he feels. The use of plants like corn, tobacco and cotton become such an important part of our lives that they play a central role in our evolution, and lead to everything from War to Prohibition.

Tools and machines have allowed us to overcome our physical limitations, and become the most successful species on Earth. But tools are also transforming what it means to be human.

Five thousand years ago man first throws a handful of rocks into a campfire and stumbles upon a discovery that changes the world: Metal. Copper, Tin and Bronze empower the ancient world and allow empires to expand, armed with sharp, hard-wearing weapons.

Early man rubbed two sticks together and created fire. We learn to cook our food, saving vital energy. As a result, our brains expand--making us the most intelligent species on the planet. Armed with fire, we experiment by heating minerals to make stronger tools allowing us to fight wars and build civilizations. But burning wood destroys our landscape, so Mankind exploits a new energy--oil.

15,000 years ago man and the wolf form a partnership that shapes the future of Mankind. With the help of man's new best friend we domesticate more animals, sowing the first seeds of farming and civilization.

Communication is the vital ingredient in the building of civilization. The ability to share complicated ideas allowed early man to hunt, farm and build communities. And the creation of things like a 22-letter alphabet and the printing press allow Mankind to further expand, leading to the proliferation of new ideas and revolution.

There are 800 very old, very mysterious, man-made stone sites in the Northeastern part of the United States. Forensic geologist Scott Wolter heads to rural Pennsylvania to investigate one of them--a meticulously crafted stone chamber buried underground in the woods. When he realizes it may have been a ritual bath chamber for a secret society, he embarks on a quest for answers as to who built, when and why.

Man uses plants to feed, heal and clothe himself, to build his world and even to alter how he feels. The use of plants like corn, tobacco and cotton become such an important part of our lives that they play a central role in our evolution, and lead to everything from War to Prohibition.

Best-selling author Brad Meltzer and his team try to penetrate Bohemian Grove, one of America's most tightly guarded gatherings of the rich and powerful. The Decoded team converges on the group's hideaway in a northern California redwood forest to pursue rumors of ritual sacrifice and secret agreements that control the lives of everyday Americans. Brad soon finds out just how difficult it is to uncover Bohemian Grove's secrets. He knew sending the team into the Grove would be risky, but he never expected they'd be calling him for bail money.

As head of the powerful 15th-century Florentine family, Lorenzo de' Medici was the ultimate Renaissance man. The leadership of Lorenzo and his family created an atmosphere of culture, sophistication, and wisdom that enabled Leonardo da Vinci, Michelangelo, and Botticelli to flourish artistically. Just as skilled at politics, the wealthy Medici ruled Florence for centuries without holding an office. Their power to bestow and withhold favors made them feared and revered, loved and hated. On April 26, 1478, a gang of men repeatedly attacked Lorenzo and his brother Giuliano with knives in the Duomo cathedral during high Mass. Giuliano died, but a wounded Lorenzo survived. For centuries, historians believed the Pazzi family, Medici banking rivals, were at the center of the complex plot. Now, Dr. Marcello Simonetta, a historian at Wesleyan University, offers a shocking twist. Did the Pazzi Conspiracy include a much broader range of perpetrators, reaching all the way to the Vatican?

In March 2002, in Vilnius, Lithuania, construction workers uncovered a mass grave filled with close to 2,000 skeletons. Scientists determined that the remains belonged to the last remnants of Napoleon's Grand Army retreating from Moscow in 1812. The find offers new insight into Napoleon's invasion of Russia, the largest military disaster ever recorded. Follow scientists as they seek to learn who these people were and how they died. Was it a massacre, an epidemic, or the result of brutal cold?

From a once seething, hellish mass of molten rock to the world that inhabits life today, take a rollercoaster ride through the entire history of Planet Earth. Its 4.5 billion year epic, a story of unimaginable timescales, earth-shattering forces, incredible life forms, radical climates and mass extinctions. Discover how the continents were formed, canyons were carved, and why the world's animals live where they do.

What if I told you that the Mafia and organized crime have taken on a brand new look that most people would never recognize? Today's mob has evolved into something more powerful, sophisticated and deadly than ever. Starting with Al Capone's notorious Chicago Outfit, Decoded traces the progression of the mob from Whitey Bulger's fearsome Irish Mafia, to today's Mexican cartels who are bringing their violent operations onto American soil, and the Cyber Mafia--online gangsters who can steal your money and identity without leaving their home. So what exactly does the new Mafia look like today, and what can we do to protect ourselves?

In our lifelong battle to fight friction, Grease--in all its forms--is the unsung hero. Journey deep into places few people ever get to see, to discover the "hidden" uses of one of our most slippery products inside giant machines. We'll also investigate how it's made in a factory in New York, as well as what new advances some are working towards for grease of the future. But in the meantime, we'll witness how it is currently used inside a US Navy aircraft carrier, San Francisco's famous cable cars, elevators and escalators, assembly lines, huge excavators, amusement park rides, and even the Panama Canal. From pig fat to nano-particles... amazing Grease keeps everything rolling along--smooth and fast.

Enter the amazing and ingenious ultra-sturdy shelters, machines, containers, materials and packaging designed to deny the ruination of society. The drive to create the indestructible has inspired some of the most prolific and awe inspiring results: The Cold War spawned personal bomb shelters in the 1950s. They weren't truly safe and secure, but today's 21st century version will last a millennium. And so will the special food you can get, along with all the comforts of home--like running water, plumbing and electricity. Caskets serve as our final resting place, but how long do they really last? Investigate how valuable data from a plane crash survives in a "black box" (that's not really black), to explain what might have caused the accident. And get an intimate look at the new "home" that protects and preserves one of the world's most valuable documents--the case that houses the original Declaration of Independence.

Discover that the deadliest snakes, sports and weather events are closer and more treacherous than you think. Travel to the slopes of Mt. Rainier, America's most dangerous volcano, and find out why 100,000 people could be in serious trouble. Watch where you step, because the most dangerous snake in the U.S. slithers in great numbers and has a short temper. Learn where the most dangerous weather phenomenon, the tornado, can cause the most damage. We'll look for protection for the most dangerous hits football can muster.

The world's largest, most active volcano system exists in the western US. 6,000 years ago, the Yellowstone Volcano erupted. Lava and pyroclastic flows covered 3,000-square miles with ash 3-feet thick. Fossils discovered as far away as Nebraska were found to have died from inhaling the Yellowstone debris. If--or perhaps we should say when--it erupts again, the Yellowstone "Mega-Volcano" will create a global cataclysm beyond human comprehension. Everything within 150 miles--including the cities of Cody, Wyoming and Bozeman, Montana--will be hit by an 800-degree blast of heat and 200 miles-per-hour winds. Thousands will be killed. That's just the local effects. Half the US will be buried beneath a blanket of volcanic ash. Crops in the Midwest--the world's breadbasket--will be destroyed. And it will take years before crops can grow again. Starvation, epidemics, and social chaos won't be long in coming.

Hawaii, 1868. The volcano, Mauna Loa, in its most spectacular eruption, spewed out enough lava to cover 40 percent of the Big Island. A similar eruption occurred in 1950. Now that the island has become developed, the potential for damage and loss from a major eruption is astronomical. Small villages have been replaced by large tourist resorts and luxury homes. Using state-of-the-art computer animation, take a look at how an event similar to 1868 would impact Hawaii. Watch buildings crumble during large earthquakes, see homes and resorts destroyed by speeding lava, and what's left of the island drown under tsunamis and mudflows. Thousands of people could be dead and the economy of this island paradise would be destroyed for years to come.
