ln 1942 through an horrific process of trial and error these Nazis created something entirely new in History - killing factories capable of murdering millions. With the increase in killing at Auschwitz and nearby Treblinka, people are showing tremendous courage, like German officer Albert Battel risking his life to save detainees.

This episode focuses on the Jurassic period, a time when the first giant killers stalked the Earth and lurked in the seas; a time when the slightest advantage meant the difference between life and death. In North America the iconic allosaurus, an ambush hunter with a lethal bite, dominated. Not even the heavily-armoured stegosaurus was safe from this killer, and incredible evidence reveals a glimpse of a vicious battle between these two giants. Life in Jurassic oceans was no easier; in 2008, a fossil was dug out of a frozen island high in the Arctic. It was a colossal marine reptile, twice as big as most ocean predators, at 15 metres long and weighing about 45 tonnes. This was Predator X. Its skull alone was nearly twice the size of a tyrannosaurus rex's, and its bite force unmatched by anything in the Jurassic seas. The balance of power between predator and prey is a fine one, as prey continually evolves different ways to avoid predators. But for the most successful and enduring predators, the battle to survive has always been tipped in their favour

Heart disease is the number one cause of deaths worldwide, killing more than eight million people each year. Cardiac infarction, more commonly known as a heart attack, can happen without warning, killing heart muscle cells immediately. Even if the patient recovers, the damage to their heart may not.
But there are researchers frantically working to change that. Meet the people inventing the future of cardiac health, from new ways of imaging the body, to the possibility of 3D printing a functioning heart.

The film examines the profound claim that most, if not all, of the degenerative diseases that afflict us can be controlled, or even reversed, by rejecting our present menu of animal-based and processed foods.
Despite the most advanced medical technology in the world, we are sicker than ever by nearly every measure. Cases of diabetes are exploding, especially amongst our younger population. About half of us are taking at least one prescription drug and major medical operations have become routine. Heart disease, cancer and stroke are the country's three leading causes of death, even though billions are spent each year to 'battle' these very conditions. Millions suffer from a host of other degenerative diseases. Could it be there's a single solution to all of these problems?

The film is an immersive chronicle of the insurrection at the U.S. Capitol on January 6, 2021, when thousands of Donald Trump's followers from across the country gathered in Washington D.C. to protest the results of the 2020 presidential election, many with the intent of disrupting the certification of Joe Biden’s presidency.
'Four Hours at the Capitol' features never-before-seen footage and vivid first-hand accounts from lawmakers, staffers, police officers, protesters, and rioters who stormed the Capitol building where the electoral votes were being counted. The film details how the violence quickly escalated, leaving Capitol security forces outnumbered and overwhelmed, and highlights the high-stakes standoff between police and rioters. The documentary presents a stark reminder of the wider ramifications of the events of that unprecedented day, which ended with the deaths of five people and more than 140 police officers injured.

It is high summer in the Polar Regions, and the sun never sets. Vast hordes of summer visitors cram a lifetime of drama into one long, magical day; they must feed, fight and rear their young in this brief window of plenty. Summer is a tough time for the polar bear family, as their ice world melts away and the cubs take their first swimming lesson. Some bears save energy by dozing on icy sun beds, while others go egg-collecting in an Arctic tern colony, braving bombardment by sharp beaks. There are even bigger battles on the tundra; a herd of musk oxen gallop to the rescue as a calf is caught in a life and death struggle with a pair of Arctic wolves. But summer also brings surprises, as a huge colony of 400,000 king penguins cope with an unlikely problem - heat. The adults go surfing, while the woolly-coated chicks take a cooling mud bath. Nearby, a bull fur seal is prepared to fight to the death with a rival. Fur flies as the little pups struggle desperately to keep out of the way of the duelling giants. Further south, a minke whale is hunted amongst the ice floes by a family of killer whales. The dramatic chase lasts over 2 hours and has never been filmed before. The killers harry the minke whale, taking it in turns to wear it down. Eventually it succumbs to the relentless battering. Finally, comical adelie penguins waddle back to their half a million strong colony like clockwork toys. The fluffy chicks need constant feeding and protection as piratical skuas patrol the skies. When an unguarded chick is snatched, a dramatic "dogfight" ensues.
