The UnXplained - Season 2 (2020)

For decades, a debate has raged over whether UFO's actually exist, or what they are. Many theories have been attributed to them, ranging from test flights of super secret military aircraft to previously unknown weather phenomena.

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? Is there really a solid core of heavy metals, or could it be a hollow environment, as many researchers claim? And just how much of mankind's history took place underground? Recent discoveries of ancient underground structures such as the city of Derinkuyu and the Malta Hypogeum suggest that there may be more structures down there, waiting to be re-discovered. If much of our past was ...

Stories of great impostors are both daring and baffling. What compels a person to attempt to become someone else? Is it merely for material gain, or to pull off an ingenious scam? Or is there a deeper reason? At one time or another, we've all fantasized about trying on a new identity, but in the case of great impostors--like Ferdinand Demara, "Clark Rockefeller" a.k.a Christian Gerhartsreiter, and Anna Anderson--their fantasies, in a sense, became reality. When does the line between impersonation and transformation get blurred? Is it possible that by pretending to be ...

Many believe it to be the Word of God, but others claim it contains inconsistencies and contradictions that could only be manmade.

From ancient civilizations to 20th century empires, mankind has had an inexplicable fascination with preserving the dead. But why? Could it be that death isn't really the end, but rather a transition to a new beginning?

Why is it that America's greatest monuments continue to enthrall us decades--and sometimes centuries--after their creation? And perhaps more importantly, what closely guarded secrets may their implacable facades be hiding?

Did Atlantis really exist? For centuries, archaeologists have tried to uncover evidence to prove that this legend is true. Will Atlantis finally be re-discovered, perhaps by employing modern technology?

For centuries, humanity has been compelled to build remarkable structures that are much more than simple places of shelter or work. What makes us want to create magnificent buildings that are bigger and grander than ourselves--and last for centuries? Whether it's Stonehenge, the Notre Dame Cathedral, or the world's tallest skyscrapers--extraordinary works of engineering are evidence of a strong instinct within us that we don't fully understand. Are we trying to prove something? Or perhaps show our power over nature? Or could there be another reason that is, for now......

Mankind's quest for gold harkens back thousands of years, but what is the special power that gold wields over our collective consciousness? Is it merely because it's rare and valuable, or could it be something more than that?

For centuries, legends and eyewitness accounts have told of a massive, hairy creature that roams the forest on two legs. While science has yet to prove the existence of this mythical man-beast, countless researchers and experiencers around the world are convinced that there is a giant, ape-like animal hiding in remote parts of the world. They point to the discovery of large, inexplicable footprints as evidence of the so-called "Bigfoot" that they hope to prove is real. But does Bigfoot actually exist?

Mysterious disappearances are confounding and bizarre and simply can't be explained. Can these be chalked up to tragic accidents? Or could they be the result of something more...UnXplained?

The total disregard for life exhibited by serial killers shocks our sense of humanity. How could human beings be capable of these horrific atrocities? And what causes such a murderous defect in the human psyche?

Experts examine some of the most devastating plagues in human history, as well as the scientific advances made in combating, or at least minimising the effects of some of these diseases.

For centuries, humanity has looked up at the Moon with a sense of wonder. But is the Moon just a rock floating in space? Or could it hold profound secrets-and perhaps even possess incredible powers? That is what we will try and find out.

Will we ever understand the motivations that drive people to undertake the most bizarre, intricate, and dangerous crimes -- or will the mind of a master criminal remain - UnXplained?
