The UnXplained with subtitle

Could a cache of fantastic riches have been buried centuries ago on a tiny island in the North Atlantic? And if such a treasure exists, who buried it? For more than 200 years, treasure hunters have been coming to Oak Island in search of a treasure that has so far eluded them all, and has even cost six men their lives. Could it be that, as legend suggests, the treasure is protected by a deadly curse?

Can humans predict the future by use of prophets and dreams, if so, can humankind harness this knowledge to avoid future deadly events.

A look at what could cause once-thriving groups of people to just abandon their great cities, never to return; modern scientific knowledge may be able to help answer the unsolved questions surrounding these lost civilizations.

Deadly dances. Masters of manipulation. Mass suicides. Murder. Many of the world’s deadliest cults ventured down dark, dangerous rabbit-holes of twisted ideologies, persuading their members to kill–sometimes other people, sometimes themselves.

A house that narrowly dodges the path of a tornado; rain that falls from the sky like blood; lightning that follows into the home.

Dracula; Lycaon of Arcadial; and the Beast of Gévaudan are the names of grotesque monsters who have reared their terrifying heads throughout history. It is discussed whether these monsters could be real.

Stories of escape that defy explanation; Harry Houdini pulls off escape acts; an attempted prison break from Alcatraz Federal Penitentiary; one man receives guidance that allows him to escape the South Tower of the World Trade Center on 9/11.

The five senses: sight, smell, hearing, taste and touch; constructing the reality of the world around us, like a blank canvas continuously painted and repainted every day.

Throughout history, many have believed that certain places, things, or even people can be tainted with dark curses. Ominous lakes that morph into watery graves. Unlucky numbers that seem to cause bad things to happen. Paintings and precious stones, which bring death and destruction to their keepers. But can these mysterious curses really have the power to bring us harm? And if so, is it possible to understand their power, or will it remain UnXplained?

For decades, the debate has raged as to what exactly Unidentified Flying Objects–or “UFOs”–really are. Theories have been put forth that attribute them to everything from secret military aircraft to weather phenomena and more. But by far, the most controversial theory is that these objects are, in fact, spacecraft that have been piloted to Earth by extraterrestrial beings. It's a seemingly outlandish notion, but could it be true? And if so, how much does the government know about these spacecraft–and the aliens who are visiting our planet?

Despite all of our modern technology and sophistication, there is much that we still don't know about what lies beneath our feet, deep underground. What is at the center of the Earth?

Today, human civilization spans the globe, and there are more than 7 billion people on Earth. But how did humanity evolve? Although many around the globe believe that the divine hand of God placed homo sapiens on Earth, were there other kinds of human-like creatures–cousins of man–that could have been just as intelligent as us? And if so, might these other species still exist today, perhaps in remote parts of the world?

Remarkable feats of engineering from our ancient past span the globe. Some are amazing in size. Others in sophistication. Some are so strange they border on inexplicable. Did the ancients have advanced scientific knowledge that has been lost to time? How–and why–did they fashion these incredible wonders?

Who was Jack the Ripper? The question has baffled police investigators, historians, and armchair detectives for over a century. Countless books, movies, and television shows have been based on the Ripper's murderous exploits each with their own unique take on the killer's identity. Was he an accomplished surgeon? A member of the British royal family? Did he actually exist at all? Over 130 years later, are we any closer to the identity of one of history's most notorious serial murderers?

Space. The Final Frontier–and the ultimate mystery. Scientists are involved in a never-ending quest to understand the vast universe our planet inhabits. But it seems that for each answer science provides, even more questions arise. Our own solar system is populated by mysterious objects and phenomenon that seem to defy our attempts to understand them. And when we get deeper into space, the mysteries only deepen. What could lay beyond the confines of the Milky Way? Are there galaxies similar to our own? Could they be capable of sustaining intelligent life? And is that life trying to contact us?

For centuries, fantastic tales of terrifying monsters have fascinated mankind. Bizarre beasts of all shapes and sizes have been portrayed in some of history's most classic stories and folklore.
