Ancient underwater cities can be found around the globe, but could these aquatic worlds be the ruins of unknown civilizations--or even proof of extraterrestrial visitations? The infamous tale of the long lost city of Atlantis may be a preserved memory of an ancient alien metropolis. Beneath Lake Titicaca in Peru, the ruins of recently discovered temples support local legends of an underwater UFO base. Ancient Indian texts, known as Sangams, describe sunken cities where aliens and humans intermingled thousands of years ago. Who could have built the 600-foot stepped stone structure off the coast of Japan--a site that may predate the Egyptian pyramids by thousands of years? Could evidence of ancient alien contact lie buried in Earth's deepest oceans?

If extraterrestrials influenced human history, can evidence of their existence be found in hidden tunnels and caverns around the world? Could a cave in Ecuador contain metallic books inscribed with secrets of alien technology? Was an ancient underground city in Turkey built with alien help... or as a refuge from an alien attack? Rumors of the U.S. military working alongside aliens in a secret base inside a mesa in New Mexico continue to swirl, Native American legends mention strange inner-Earth beings, and recent archaeological discoveries in the Yucatan may point to an extraterrestrial reality behind.

New evidence suggests there was more than one UFO crash near Roswell. On July 8, 1947 at 5:26 EDT, an Associated Press news wire announced that soldiers from Roswell Army Air Field in New Mexico recovered a "flying disk" from a nearby rancher's property. The tiny town of Roswell has never been the same. Now, 61 years later, new theories, new witnesses and new evidence have emerged. The most shocking lead is that there may have been a second crash, and if it can be found, it may finally reveal what really happened at Roswell.

On April 19, 1897, the Dallas Morning News reported a mysterious airship had crashed into a windmill in the nearby town of Aurora, Texas. Townspeople were said to have found an alien body and buried it in the local graveyard; the crash debris was dumped into a local well. More than 40 years later, the ranch owners were reporting skin lesions and crippling rheumatoid arthritis, which they attributed to tainted well water. The well was sealed over and forgotten. Now, more than a century after the event, the team will reopen the well, and search for the legendary grave, as they attempt to solve one of the earliest UFO cases ever recorded.

Rick turns up the heat when an 1881 potbelly stove whips into the shop. Can he cook this project to perfection, or will this old oven come out burnt to a crisp? And later, the guys are unexpectedly challenged to restore a 1940s children's Irish Mail cart by hand. Can they successfully conquer this manual mission, or will this rug rat ride put them in the corner?

When Rick's brother Ron and son Tyler encounter a 1950s milk vending machine for sale, they attempt to squeeze out a good deal. Can they churn something out of this dairy discovery or will one false moo-ve have them headed home empty-handed? And later, the guys restore two kiddie handcar trains from the 1950s. Can they make a perfect pair out of these rusted railroad rides, or will this amusing assignment run out of steam?

Everything around us has a story to tell. Shoes, cans, string, mirrors; everything we see and touch has an epic tale of how it came to be invented or discovered, and the dramatic moments throughout history at which it played an important role. But few of us know these stories. We go through our days blissfully ignorant of the deadly and dangerous road brave men traveled in order to bring coffee to the world, or the pivotal part beer played in the civilizing of mankind. These stories and many more are brought vividly to life in this two-hour special, which follows one man on a journey through the last day of his life, examining and recounting the epic tales of the everyday items he encounters before his ignorance of their stories leads him to his ultimate doom.

We live in a highly mechanized world in which billions of products are made by machines--but there are some things that can be built only by using an even more sophisticated tool--the human hand. In New Mexico, a pilot who builds his own jet-powered glider takes to the skies--his very life depending on his handiwork. Canoe makers in Montana, and a knife maker in Washington, handcraft items so unique that customers are willing to pay significantly higher prices than if they were machine made. In the farmlands of Central California, craftsmen keep alive the ancient art of weapon making--see their gleaming suits of armor in action, as weekend warriors do battle. Ever wonder how those impressive animal skeletons in museums are constructed? The artists of Skulls International in Oklahoma City share their secrets. And in Hollywood, the Chiodo brothers reveal how handmade special effects have a charm and character that today's computer animators can't duplicate.
