This BBC six-episode documentary film series presents the story of Auschwitz and the Holocaust through interviews with former inmates and guards and re-enactments. The first episode explores the beginnings of Auschwitz, and how the camp was originally intended for a purpose very different from that of the genocide of the Jews.

All seems lost for the Allies. The Italians are defeated at Caporette, and a Bolshevik Russia pulls out of the war. But the American reinforcements are decisive, and the Allies emerge victorious. The Allies are unable to negotiate an honourable peace agreement, and the Treaty of Versailles, 20 years later, will have disastrous

Syria Civil Defense (SCD), also known as the White Helmets, is a volunteer civil defense organization that operates in rebel-controlled Syria during the Syrian Civil War as a response to indiscriminate bombardment of civilian communities. This group of indomitable first responders risk their lives to rescue victims from the rubble.

The fifth programme explores the alliances formed between the animal and plant worlds. Attenborough dives into Australia's Great Barrier Reef and contrasts the nocturnal feeding of coral, on microscopic creatures, with its daytime diet of algae. Some acacias are protected by ants, which will defend their refuge from any predator. Besides accommodation, the guards are rewarded with nectar and, from certain species, protein for their larvae as well. Fungi feed on plants but can also provide essential nutriment to saplings (Mycorrhiza). The connection is never broken throughout a tree's life and a quarter of the sugars and starches produced in its leaves is channelled back to its fungal partners. Meanwhile, fungi that feed on dead wood leave a hollow trunk, which also benefits the tree. Orchids enjoy a similar affiliation. Lichens are the product of a relationship between fungi and a photosynthetic associate, usually algae. They are extremely slow-growing, and a graveyard is the perfect location to discover their exact longevity. Mistletoe is a hemiparasite that obtains its moisture from a host tree, while using own leaves to manufacture food. Its seeds are deposited on another by the mistletoe tyrannulet, following digestion of the fruit. The dodder (Cuscuta) is also parasitic, generally favouring nettles, and siphons its nourishment through periodic 'plugs' along its stem. The rafflesia has no stem or leaves and only emerges from its host in order to bloom — and it produces the largest single flower: one metre across.

Filmmaker Robert Kenner lifts the veil on our nation's food industry, exposing the highly mechanized underbelly that's been hidden from the American consumer with the consent of our government's regulatory agencies, USDA and FDA. Our nation's food supply is now controlled by a handful of corporations that often put profit ahead of consumer health, the livelihood of the American farmer, the safety of workers and our own environment. We have bigger-breasted chickens, the perfect pork chop, insecticide-resistant soybean seeds, even tomatoes that won't go bad, but we also have new strains of e coli--the harmful bacteria that cause illness for an estimated 73,000 Americans annually. We are riddled with widespread obesity, particularly among children, and an epidemic level of diabetes among adults Featuring interviews with such experts as Eric Schlosser (Fast Food Nation), Michael Pollan (The Omnivore's Dilemma) along with forward thinking social entrepreneurs like Stonyfield Farms' Gary Hirschberg and Polyface Farms' Joe Salatin, the film reveals surprising--and often shocking truths--about what we eat, how it's produced, who we have become as a nation and where we are going from here.

Richard Hammond explores the extraordinary wonders of the world of detail hidden in the blink of an eye. It takes our brain around a hundred and fifty milliseconds to process what we see. We're not aware of this time lag going on, but in those few milliseconds, there are extraordinary things happening that completely pass us by. But what if we could break through this speed limit? Bend and stretch time in ways never thought possible. What new marvels would we see? Now, using the latest high-speed cameras, Richard takes us on a journey beyond our eye's limits, letting us see secrets hidden in every element of our planet. A world where thin air can shatter rock. And water can tear through metal. A world where the fastest thing on earth lies right beneath our feet. And where a spectacular celestial display is finally captured, even though many have claimed it doesn't even exist.
