Welcome to Las Vegas, America's Sin City where casinos have made security their highest priority. Join hosts Don Wildman as he uncovers underground vaults, secret surveillance nerve centers, and how the latest technology beats the cheaters. Don shows how a massive engineering feat transformed the city from a barren desert into a mobster metropolis where thieves ran the show from underground tunnels dating back to Prohibition. Vegas is the only city in the world where you can be in Egypt one moment and Italy the next, thanks to a secret underground.

After the fall of the Roman Empire, Europe was plunged into chaos for centuries, with vicious carnage and rampant disease regularly raging through the streets.

Today, New York is the biggest city in the country... but it's got some dark secrets in its past. It was founded by covert groups, overrun with gangs and mob bosses, and ruled by secret societies. This is the true foundation of the city that never sleeps, and host Don Wildman is headed deep beneath the skyscrapers, taxicabs and street vendors into a New York that few have ever seen before. From a hidden Freemason tunnel and secret world of the Sandhogs, to mobster hideaways and gang escape routes, we're uncovering the secret societies that built New York--from the underground up.

The urban sprawl of Cairo, Egypt belies its history as one of the world's oldest civilizations, where the Pharaohs' ancient secrets lay hidden deep below the vast deserts of the Nile. Don Wildman embarks on an underground quest to explore the massive engineering might of the oldest structures in the world, and learn how they survived a long history of invasions by the Mediterranean's greatest civilizations: the Greeks, Romans and Turks. The Step Pyramid, constructed a century before the great structures at Giza, reveals hidden insights into how the Pharaohs died; an eerily detailed roadmap to the afterlife known as "The Book of the Dead" is examined; and a lost tomb filled with 2,000 year-old mummies is serendipitously discovered. Cairo is a city of the living and the dead, with its darkest secrets hidden in the tunnels of the ancient underworld.

World War I was the bloodiest war the world had ever seen. A young Adolf Hitler served in the trenches and tunnels of Belgium's Western Front. Join host Don Wildman as he explores the subterranean web where 24,000 Allied soldiers waited to ambush the enemy, to the indestructible fortress that endured thousands of bombs daily. Discover the underground that made World War I one of the most brutal wars in history... and turned Hitler into the terrifying madman of World War II.

The largest naval armada in U.S. history descended on the Japanese island of Okinawa in April of 1945. Instead of a swift victory for the American's it became the bloodiest battle of the Pacific. Much of the battle wasn't on land it was underneath it--from the beehive of combat tunnels to the caves where thousands of civilians hid. Join host Don Wildman as he discovers what it was like to live through the Battle of Okinawa. Watch as he delves into the subterranean tunnels, caves, and bunkers, and then dives to explore the lost naval destroyer sunken deep in the waters off Okinawa's coast.

Hundreds of ghost stories lurk in the shadows of London, England, but behind every myth and legend is the terrifying truth that sheds light on one of the darkest periods of this city's history. In Victorian times, violent crimes, extreme poverty and lawlessness forced Londoners to band together to survive. In a time when science and medicine challenged the Church, and disease and overpopulation drove the poor to do jobs only the Devil himself could imagine, London set the stage for chaos. From body snatchers and serial killers to occult clubs and pagan rituals, Victorian Londoners lived by their own rules...both above and below ground. Don Wildman explores London from the bottom up and tells the stories most would rather remain buried.

In days of old, if your army had to take on a huge stone castles there was only one option: bunker busting siege weapons like the giant crossbow known as the Ballista and the fearsome Trebuchet! These weapons hurled rocks and flaming kegs to cause mayhem and smash through walls. Today the siege tradition continues, with our military using high-explosives to blow the bad guys out of their foxholes. First, Gunny let's loose massive boulders from an ancient trebuchet catapult against an enemy castle. Then he gets his hands on some old-style gunpowder and recreates the big bangs that were used to bring down enemy bunkers, all the time instructed by committed experts who revel in the history of these amazing weapons. Gunny also visits today's bunker busters--military engineers who bust under, over, and into enemy strongholds.

Gunny takes a journey through the history of cannons and field artillery and shoots off everything from Revolutionary War-era cannonballs to the futuristic shells of NLOS-C -- a fully automated piece of artillery that's so new the Army's still testing it. Other featured artillery includes Civil War cannons and the Pack 75 Howitzer, a World War II cannon used in the Battle of the Bulge.

A stunning documentary about the escalating global nuclear arms crisis. Traces the history of the atomic bomb from its origins to the present state of global affairs: nine nations possess nuclear weapons capabilities with others racing to join them, with the world held in a delicate balance that could be shattered by an act of terrorism, failed diplomacy, or a simple accident. Written and directed by acclaimed documentarian Lucy Walker (Devil's Playground, Blindsight), the film features an array of important international statesmen, including Jimmy Carter, Mikhail Gorbachev, Pervez Musharraf and Tony Blair.
