Original subtitles

NARRATOR: Worldwide, 36 billion cameras

are watching us on our streets, at work, and in our homes.

They capture things that seem impossible.

Science says this shouldn't happen.

WOMAN: Do you say that?

NARRATOR: Experts carry out forensic analysis

of these unusual events.

Wow.

What a blast.

This doesn't make sense.

There has to be some sort of explanation.

What else is going on here?

NARRATOR: Coming up, in Brazil, a door to the land of the dead.

This is what nightmares are made of.

NARRATOR: Is this Adolf Hitler's final act of revenge?

Could this be one of Hitler's unexploded bombs?

Pull!

NARRATOR: And is America being invaded--

NARRATOR: --by an African super predator?

They snatched a two-year-old child, literally tore his arms

off, and pulled out his kidney.

NARRATOR: Bizarre phenomena.

Oh my gosh.

Ah!

NARRATOR: Mysteries caught on camera.

What's the truth behind this strange evidence?

Curitiba, a city in southern Brazil.

March 13, 2017, 2:30 AM.

[thunder]

Two security guards on patrol in a municipal building

investigate a disturbance in the basement.

They begin to film.

GREG SZULGIT: You can imagine what's

going through these security guards' heads.

This is like a nightmare.

They're patrolling an empty building,

and the lights in this hallway are flashing off and on.

Suddenly there's this door in the distance making

an ominous banging sound.

And the banging repeats.

The night is punctuated by this slamming sound

of a metal door opening and closing

and opening and closing.

[banging]

NARRATOR: Locals claim the building has

a disturbing past, a past that's left some kind

of angry ghostly presence.

GREG SZULGIT: Bam, bam, bam.

Then as they approach and get really close,

the door stops moving.

NARRATOR: Then total darkness.

The shaken guards refuse to discuss

their experience in public.

I wouldn't be surprised if one of these guys

needed a new pair of underwear.

NARRATOR: Historian Tony McMahon discovers

that belief in the supernatural in this area of Brazil

is common.

More than 1 in 10 people claim to be able to communicate

with the dead.

Mysticism and magic are very strong in Brazil,

and there's a huge belief in something called [portuguese],,

a kind of form of voodoo.

And with this is a sense that the dead

can exert a malign and evil influence over the living.

NARRATOR: Believers claim angry spirits can bring

illness, misfortune, and death.

Even the country's leaders are said

to dabble in this dark art.

In 2017, acting President Michel Temer and his beauty queen

first lady are driven from their palace

by what they describe as evil spirits.

In the [portuguese] belief system,

a dead person could be trying to signal their deep

unhappiness through the slamming of a door, as in this instance.

[banging]

NARRATOR: But professional magician

Ben Nemzer is suspicious.

BEN NEMZER: It got faster and faster and louder and louder

as the guy got closer.

And as a magician, I don't believe

in coincidences like that.

It has to be that there was someone

trying to scare those people.

NARRATOR: Explorer George Kourounis wonders if this could

be a sign of criminal activity.

Locals believe that there are violent spirits living

in the basement of this building,

but it might all just be a smokescreen for a much

more sinister practice.

One of the most vile crimes that we see in this area

is the illicit organ trade.

NARRATOR: In Brazil, almost 10 million

people live in extreme poverty.

Desperate Brazilians earning under $2 a day

advertise their kidneys online for up to $10,000.

Illegally trafficked organs make up 1 in 10 transplants,

netting crooks almost $2 billion a year.

In 2012, a woman advertises her kidney for sale,

but she's so desperate she updates

the post to add part of her liver,

her corneas, and one lung.

But not all organs are given up voluntarily.

Over 8 million children live or work on the streets.

Charities claim helpless kids are increasingly

the target of organ thieves.

A building like this is a great place for organized crime

to base their appalling operations,

including the harvesting of children's organs.

NARRATOR: But investigators discover

no reported criminal activity in the building.

GREG SZULGIT: The doors not just, like,

blowing in the wind.

Something must be moving in forcefully.

NARRATOR: Greg Szulgit investigates weather reports

and discovers a huge thunderstorm

hits the town on the night of the supposed haunting.

The flickering lights might suggest that there's

something electrical going on.

NARRATOR: Brazilian lightning strikes kill

over a hundred people a year.

Electrical engineer David Wallace

wants to know if it's possible for electrical storms

this fierce to create poltergeist-like effects

on inanimate objects, such as the metal door in the basement.

This area of Brazil averages over 80% humidity,

meaning the air is saturated with water.

So when you have dense, humid air,

you have the possibility of conducting

electricity through it.

NARRATOR: Wallace and his team test if electrical charge

in the dense, wet area of the basement

could cause the door to somehow swing on its hinges.

To mimic the door in the footage,

they set up a negatively charged sheet of aluminum foil

next to a positively charged metal plate

representing the door frame.

We will run a voltage on this plate, and we will see,

will it pull the door to the plate?

And we'll see if we can recreate what I am seeing in the video.

Energize.

NARRATOR: Coming up, a deadly energy lurks

in the air of the basement.

Is it a physical phenomena that's

there or some unseen force?

We need to find out.

NARRATOR: And is this--

[explosion]

--the Nazis' last revenge?

That was quite a bang.

[thunder]

NARRATOR: In Brazil in a municipal building

that is said to be haunted, a door

is filmed slamming by itself.

Electrical engineer David Wallace fixes up an experiment

to see if the region's electrically

charged atmosphere is causing this

poltergeist-like phenomenon.

He charges his generator with high voltage.

I actually have a 100,000-volt generator sitting right here.

OK, let's get right to energize the system here.

Energize.

NARRATOR: 30,000 volts course through the plane,

pulling the foil toward the charge.

DAVID WALLACE: Take it off.

So here we see something very similar to what

we saw on the video.

I have a metal plate inside a metal fixture.

And as I increase the voltage, what we

see as the higher the voltage goes,

it actually pulls the plate over towards the fixture,

just like we saw in the video.

NARRATOR: Wallace shows it's possible for an electrically

charged atmosphere to swing a piece of metal haunted

house-style on its hinges.

But when engineer Jon Farrow studies the plans

of the building, he notices its air shouldn't

become electrically charged.

Buildings in this part of Brazil

are designed to carry lightning from the top

down into the ground, and this is called grounding.

NARRATOR: Lightning rods carry the massive electrical strikes

around the outside of buildings and stop metal objects getting

charged with high voltage.

If the system is broken, the people

inside will be left dangerously exposed

to deadly lightning strikes.

But until the security guards reveal more details about what

they saw that night, the cause of the slamming door

remains a mystery.

I don't care what the security guards are being paid.

It's not enough.

NARRATOR: Now, the southern Russian city of Volgograd.

August 10, 2020, 12:40 PM.

Rush-hour traffic comes to a halt

as a sinister black cloud rises above the road.

A local man captures the event on his phone.

We're looking down the road.

In the distance, we see smoke rising.

NARRATOR: And then.

[explosion]

MARTIN MORGAN: Kaboom.

This fireball looks like it goes 300 or 400 feet into the sky.

[bleep]

He's clearly so mesmerized by the explosion

that he doesn't realize his life is in danger

and he should get out of there.

This is a cataclysmic explosion,

and it's coming towards you.

NARRATOR: And this is no ordinary blast.

This doesn't look like a regular explosion.

It's building energy with every second.

NARRATOR: Locals fear their city is under attack.

This looks like something out of a war movie.

NARRATOR: Historian Craig Gottlieb discovers

Volgograd used to be known by a different, more infamous name.

This explosion is in Volgograd, which during World

War II used to be Stalingrad.

NARRATOR: August 23, 1942.

Adolf Hitler orders his feared 6th

Army and 4th Panzer division to take the city by any means.

Russia's leader Joseph Stalin commands his Red Army

to halt the Nazi advance at all costs.

It's the single-deadliest battle in world history.

The Nazis surrounded Stalingrad,

starving the population.

Stalin was so intent on winning this battle

that he kept the civilians in the city

and refused to allow them to escape.

Why?

Because he figured that his forces

would fight harder if civilian lives were at stake.

NARRATOR: Stalin's brutal order might

have motivated his troops, but it comes at a terrible price.

But in those months that stretch between August

and February, the city of Stalingrad

is turned into hell on Earth.

NARRATOR: 2 million soldiers and civilians die in the battle

for control of Stalingrad.

And even today, mass graves are still

being discovered in the city, many containing

hundreds of skeletons.

But bodies are not the only horror being unearthed.

So is a deadly legacy of the Luftwaffe.

The bombing was so intense that the Nazis flew over 10,000

bombing missions over the city.

Seeing a massive explosion like this,

there's the possibility that we're

looking at an unexploded bomb from the Second World War.

[explosion]

[bleep]

NARRATOR: Hitler ultimately lost the Battle of Stalingrad,

but his ability to kill Russian citizens

continues decades later.

JEFF WISE: You know, the chemicals

that these bombs are made out of over time deteriorate, decay.

Then just, you know, out of nowhere, boom.

NARRATOR: Matt Kutcher is a Hollywood

pyrotechnic and ballistics expert with over

two decades' experience.

In this city of Stalingrad, we know

that Hitler dropped a thousand tons of explosives

in just one day.

Quite often we find that ordinance that hasn't exploded,

it's usually been buried.

NARRATOR: Matt's been looking at original blueprints

of Nazi ordnance.

OK, son, be careful.

What we're going to have to do here

is create our own Hitler bomb.

All right.

NARRATOR: This is a recreation of a Nazi high-explosive bomb.

Over a million were manufactured during World War II.

We're going to place it under the ground subterranean.

All right, grab some shovels, son.

Right about here is good.

We're going to attach charges to it,

and we're going to blow it up and see if that type of HO

explosion, a High Order explosion,

matches what we see in this video.

NARRATOR: Coming up, can Matt Kutcher

discover the truth behind this devastating explosion?

[explosion]

3, 2, 1, go.

Oh, that's a blast from the past.

NARRATOR: And has a Mississippi swamp

become planet of the apes?

I'm thinking it's going to come over and rip me to shreds.

[explosion]

[bleep]

NARRATOR: Volgograd, Russia, is rocked by a massive explosion.

Pyrotechnics expert Matt Kutcher has built and buried

a replica Nazi bomb to see if the blast in the footage

was caused by a piece of unexploded ordinance

dropped by Adolf Hitler.

5, 4, 3, 2, 1, go.

[bleep]

That's a blast from the past.

All right, let's go see what we did.

I actually saw the shockwave from my naked eye up there.

I was able to see the initial burst,

and then the wave come traveling and went up and out.

Yeah, it was very cool.

NARRATOR: Matt analyzes the footage of the Volgograd blast

and compares it to his own imitation Nazi bomb.

MATT KUTCHER: In our explosion, you saw a lot of debris

in the blast wave, but clearly that's

not what we see in the video.

[explosion]

[bleep]

It's a massive fireball that takes

up the whole end of a street.

NARRATOR: Most Nazi bombs didn't use a fireball

to destroy their targets.

They killed by creating a shockwave,

smashing bodies and objects that fell into their path.

MATT KUTCHER: So clearly it wasn't ordinance that went off.

So it must be something else.

NARRATOR: Former NYPD image analyst Conor McCourt

studies the footage for clues.

He notices an unusual detail just before the fireball.

CONOR MCCOURT: There's different stages to this explosion.

We're initially seeing a black plume of smoke,

indicating a fire.

What I'm noticing here is this looks like smoke,

but this is not smoke.

This is some kind of chemical cloud

that ignites into an explosion.

If I'm looking for the source of this white cloud,

one of the possibilities is a gas station.

NARRATOR: Russia produces more than 12%

of the world's oil and gasoline, over 11 million barrels a day.

MARTIN MORGAN: Volgograd is within a region

that's oil rich.

So gasoline is cheap over there.

The big problem, though, is that wages are also extremely low.

That's going to lead toward a black market.

NARRATOR: Fuel theft in Russia happens on an industrial scale.

In 2009, thieves siphoned off 27,000 tons of oil

from a pipeline in the Dagestan region.

Such pipelines are now heavily guarded,

so criminals look for softer targets.

Gas stations have hatches.

And if you open that up, you're going

to get access directly to the storage

tank of the whole gas station.

Criminals have these specially equipped vans,

drive over the hatch in the ground, open your hatch,

suck up the gas, and drive off with it,

leaving a baffled and impoverished gas-station owner.

NARRATOR: But hijacking fuel is a high-risk enterprise.

These criminals are literally playing with fire.

If something goes wrong, there's a spark,

boom, massive explosion.

MARTIN MORGAN: It could be the crime in progress that has gone

wrong that produced the explosion that has

created this massive fireball.

NARRATOR: Photos confirm the center of the blast

was a gas station.

This huge explosion ripped through a 10,000-square-foot

area of downtown Volgograd.

Miraculously, only 13 people were injured.

And while no one was killed, the people of Volgograd

fear that next time they might not be so lucky.

What took Hitler and the Nazis six months to accomplish,

the destruction of Stalingrad, a couple of gas thieves

could accomplish the same goal in seconds.

NARRATOR: Now the southern state of Mississippi.

October 24, 2013.

A man exploring some of the state's

19 million acres of untamed forest and swampland stumbles

on an incredible scene.

[insects chirping]

It just looks like a landscape with swamp trees,

but then suddenly a dark figure is

seen there moving among them.

NARRATOR: The hiker films with his camera phone

while something black haired and enormous

seems to be tearing at a cypress tree.

This thing is massive.

It doesn't quite look like a bear.

I've never seen anything like that.

NARRATOR: The creature seems to have incredible strength.

LYLE BLACKBURN: This is a cypress tree.

These are strong trees, but this creature is literally ripping

it off with his bare hands.

NARRATOR: Suddenly the beastly figure

seems to sense the presence of the hiker and rears up.

It looks like it's displaying a sign of aggression.

NARRATOR: The man pleads for his life.

I can see why he's so scared.

This thing is massive.

I've studied mammals in North America for years,

and I've never seen one with this form and this kind

of destructive behavior.

NARRATOR: Coming up, is one of nature's

most aggressive primates on the loose in the woods?

This thing would have terrified the hell out of me.

NARRATOR: And a mysterious invasion

in the Midwestern skies--

WOMAN: Oh my god.

Oh my gosh.

That thing is huge.

NARRATOR: --targets America's nukes.

Are we in danger from an unknown enemy here?

NARRATOR: In a Mississippi swamp,

a hiker encounters a hair-covered beast

tearing at a tree.

NARRATOR: Biologist Roland Kays believes

the creature in the footage may be a deadly African animal.

There are people in North America who keep chimps as pets

or keep them in sanctuaries.

Is it possible that we're seeing an escaped pet chimpanzee?

NARRATOR: Chimps are highly intelligent,

aggressive, and territorial.

They use simple stone tools to forage for food

and are almost twice as strong as a human.

In Africa, there are over a quarter of a million chimps,

and they occasionally kill humans.

In 2014, a troop targeted a village in Uganda in Africa.

They snatched a two-year-old child, literally tore his arms

off, and pulled out his kidney.

And this started a reign of terror

that ended with two more children

dead and six badly injured.

[chimps calling]

NARRATOR: Mississippi hunters David Childers and Peyton

Lassiter claim to have encountered

the beast caught on camera by the hiker

while out in the local woods.

They say it has all the aggressive qualities

of an alpha male chimp.

DAVID CHILDERS: Whenever I saw this creature,

I was hoping it would not see me.

As I'm standing there in complete shock,

I mean, I'm thinking, hey, look, if this thing sees me,

it's going to come over, rip me to shreds.

NARRATOR: The swampy forests of Mississippi, where temperatures

can soared to 115 degrees, are similar to the jungle

environments of Central Africa where chimpanzees

have their natural home.

The fact that Mississippi is a very, very raw landscape,

not heavily populated, it is quite

possible for a creature of that stature to make it a refuge.

NARRATOR: In 2020, a couple camping nearby

with their pet dogs see what appears

to be a chimp-like creature watching them from the woods.

And then this thing starts throwing rocks and small trees

at them.

NARRATOR: The couple, fearing for their lives,

set their dogs on the attacker, a fatal mistake.

Then suddenly the creature was throwing something else

at the tent, pieces of dog.

This thing right here would have definitely

terrified the hell out of me.

Oh yeah.

NARRATOR: But biologist Steve Potvin

compares the creature in the footage

to images of chimpanzees and finds they don't match.

It's too big to be a chimpanzee,

and the ratio of the body to the legs

doesn't quite match that of a gorilla.

NARRATOR: The dimensions of this creature correspond

to no ape known to science.

Until the man who shot the extraordinary footage comes

forward to give more details about this creature,

its true identity will remain a mystery.

But for some of the hunting community in Mississippi,

there is no doubt that the film is a glimpse

of something truly terrifying.

It is highly likely that a creature of significant size

could be hiding out in the wilderness.

No doubt about it.

NARRATOR: Now, this small Nebraska town of Hastings.

January 4, 2020.

Jackie Hoffman witnesses something

mysterious in the sky.

She grabs her cell phone and begins to film.

It was like a machine, and it had,

like, lights shining off of it, and it was going really fast.

It was so close to our apartment complex.

That's kind of what scared me the most.

NARRATOR: And this is no isolated close encounter.

In the following days and months in Colorado, Kansas,

Nebraska, and Wyoming, reports flood

in of similar craft in the sky.

WOMAN: Oh my God.

WOMAN: This is hovering there.

Sometimes people only see a single mechanical object

in the sky.

Other times people are seeing a whole swarm.

NARRATOR: Nebraskan Eric Eckert films the craft from his porch.

These weren't just some hobby drones.

They were flying much faster, 60-plus

miles an hour over super-long ranges at night.

It told me that, you know, maybe something

that had a better technology was running this sort of stuff.

NARRATOR: Locals demand answers.

Analysis of the flying objects reveals

them to be large, unmanned aircraft,

but neither the American government

nor any American corporation claim to have

any knowledge of what they are.

It seems wild to me that hundreds of people

can see the same event and we still

don't know what's going on.

NARRATOR: A spate of similar sightings

of aerial objects over the same states occurred in the 1970s.

Farmers would go out to the fields,

and they would start seeing all of these strange objects

flying up in the sky.

NARRATOR: And these objects in the sky

seemed to bring a wave of death in their wake.

So these farmers would go out, and they would find

their cows dead on the ground.

NARRATOR: More than 1,500 cattle across the Midwest

are sliced up with apparently surgical precision.

Wild rumors circulate that the mutilated animals are being

butchered by visitors from another world,

and no culprit is ever apprehended.

So it's no surprise when you see

these mysterious crafts that people

don't start getting worried.

NARRATOR: Coming up, reports reveal a sinister craft

meddling with nukes.

Several of the ballistic missiles

were no longer capable of launch.

NARRATOR: And a private jet burns on a state highway.

Has the pilot paid the ultimate price for failure?

These are some of the most violent

criminals on the planet.

NARRATOR: In the Midwest, eyewitnesses across four

states film unknown craft invading the skies.

I know there was rumors going around

that it was the government spying on us

or trying to look for something.

NARRATOR: But journalist Jeff Wise

uncovers troubling evidence the flying machines are

not American and are actively blocking

attempts to identify them.

So the government launched a surveillance plane equipped

with sensors that could detect the heat

signature of these mechanical objects,

but they came back without any useful data.

NARRATOR: The government cannot explain the threat,

but Wise maps the sightings and believes whoever is controlling

these machines seems to be targeting

America's atomic defenses.

One of the things that I uncovered

is that this area has a lot of nuclear missile silos.

NARRATOR: It reminds historian Marty Morgan

of an event at a facility in Montana recounted by Air Force

launch officer Robert Salas.

In the 1960s, there was a UFO encounter

over Malmstrom Air Force Base.

These lights in the sky appeared.

NARRATOR: Salas reported the red, glowing object had

an alarming effect on the nuclear missiles stored

at the top-secret facility.

The men on duty discovered that several nuclear missiles

were no longer capable of launch.

NARRATOR: US authorities deny the incident ever happened,

but several eyewitnesses come forward

to confirm Salas's account and insist a terrifying breach

of national security occurred, perhaps

by a foreign power or even an unknown enemy.

Maybe what we're seeing now is related to this sighting

from the 1960s.

And so now we have to be concerned about an enemy who

might infiltrate the United States

and attack our nuclear facilities.

NARRATOR: The detonation of just one

intercontinental ballistic missile in a Midwest silo

could kill over a million people.

The fallout cloud afterwards would expose 650,000 more

to an agonizing death by radiation poisoning.

And the strange craft continue to be seen

while evading identification.

We still don't know who's responsible for these flights.

And until we find out, we have a national-security crisis

on our hands now.

Something has to be done to address this.

NARRATOR: Now, the Mexican seaside state of Quintana Roo.

July 5, 2020.

Antonio Carlos Hernandez and two friends drive

the Carrillo-Mérida highway.

NARRATOR: An ordinary trip to the beach

takes a strange and sinister turn.

Helicopters buzz in the sky, and smoke rises in the distance

as they round the corner into a scene straight from hell.

NARRATOR: The burning wreckage of an aircraft

straddles both lanes of the highway

with no signs of human life.

So as the burning plane comes into clear focus,

I can't tell if people are inside

and are stuck and can't get out.

If I saw a plane in the middle of the highway,

I would be terrified.

We need to know what's going on.

NARRATOR: Coming up, is this the final flight of a man

who has failed a drug baron?

Retribution in the Mexican drug cartels

is both swift and harsh.

NARRATOR: In Mexico, a raging inferno engulfs a plane ditched

in the center of the highway.

Engineer Nick Householder examines the shape and size

of the aircraft and discovers it's

a model only used by the richest people in the world.

Looking a little closer, the plane

appears to be a BAE 125, which is one of the world's first

and most popular private jets.

NARRATOR: Flying in a private plane

is 19 times more dangerous than getting in a car.

16 people die in 2008 when a private plane

smashes into rush-hour traffic in Mexico City.

But Householder's zooms in on the wreckage

and discovers evidence this plane hasn't crashed.

NICK HOUSEHOLDER: All the wheels are down.

This looks like an emergency landing.

In an emergency situation, a pilot could

try to land on the street.

NARRATOR: And when engineer Brian Wolshon examines

the plane in detail for faults that could have brought

it down, he sees there is something

odd about the raging inferno.

So one of the most logical places of fire on an airplane

is the engine or perhaps the fuel tank.

What we see is the fire is actually in the fuselage

itself.

Perhaps someone was trying to start a fire

to hide or burn evidence.

NARRATOR: Mexico is engaged in a violent war against

super-wealthy drug traffickers.

South American cartels export over a thousand tons of cocaine

every year, much of it through Mexico to the United States.

Now, planes like this are rumored

to be really popular with drug cartels for running drugs.

NARRATOR: The cartels pull in over $39 billion a year

from drug sales in the US.

Nick Householder discovers reports

of second-hand or out-of-date private jets bought

up for around $1 million each.

The seats are stripped out, and they are loaded up

with up to $100 million of cocaine for a journey

from the jungles of Central America to the USA.

Cartel pilots are paid up to $500,000 for a single flight,

but the risks are enormous.

Some drug cartels have been known to use the rainforest

as a location to build makeshift runways by cutting

down patches of trees.

The planes fly in with no lights, overloaded,

and guided by drones.

NARRATOR: Incredibly to the super-rich cartels,

million-dollar planes are considered disposable.

A million dollars isn't that much

when you think they're carrying $100 million of cocaine

on every flight.

NARRATOR: Over 50 crashed or abandoned so-called narco jets

are discovered ditched in the jungles of Central

America in 2019 alone.

Journalist Liberty Vittert examines the footage further

and spots the helicopter in the sky

belongs to the Mexican military.

She finds a report that confirms her suspicions.

The report says that the Mexican authorities

deployed a counternarcotics team via helicopter.

The passengers quickly departed and then rendezvoused

with the truck waiting nearby.

NARRATOR: But the chopper chases down and seizes the truck

and discovers $5 million worth of cocaine.

The pilot sets fire to the cockpit to cover his tracks.

This guy hasn't just missed out on a half million dollar

payday.

He's messed up a drug drop, so he'll also

now be fearing for his life.

Retribution in the Mexican drug cartels

is both swift and harsh.

They're some of the most violent and dangerous criminals

on Earth, and they're only getting

more brutal in their methods.

NARRATOR: Over 90 people a day are

murdered by the cartels in Mexico, many decapitated

or dissolved in acid, victims of turf

wars, disloyalty, or failure.

So the loss of over $5 million in cocaine for these pilots

has got to be a very bad day.
