The contests between predators and prey are the most dramatic events in nature. Taking an intimate and detailed look at the remarkable strategies employed by hunters to catch their prey and the hunted to escape. Sir David Attenborough narrates. "The Hardest Challenge" reveals the extraordinary range of techniques predators use to catch their prey - from a leopard using all its powers of stealth to stalk impala in broad daylight to wild dogs, whose tactic is to wear down their prey over long distances; from Nile crocodiles, the planet's most patient predators, to killer whales who use teamwork and intelligence to take on humpback whales. But even with these finely tuned strategies, the outcome is far from certain. Surprisingly, most predators fail most of the time.

The film documents the historic journey of a team of adventurers as they strive to complete the world's first completely human powered ocean row from Cape Horn to the Antarctic Peninsula across The Drake Passage, the most dangerous 600 miles of open ocean on Earth.
The expedition was captained by Icelandic explorer Fiann Paul, who was joined by a team of six record-holding explorers and athletes from four nations and three continents, including Colin O'Brady. The row pushes the entire crew to their limits, testing their physical and mental strength as they work to accomplish something many think was impossible.

China's last empire, the Qing, lasted from 1644 to 1912. It began in violence and war as the Manchus swept down from the north, but invaders became emperors, with three generations of one family ruling the country. Among them, Michael Wood argues, was China's greatest emperor - Kangxi. Under the Qing, China doubled in size to include Xinjiang in the far west, as well as Mongolia and Tibet, creating the essential shape of China today. The new dynasty tolerated a diversity of cultures and religions, including Islam. In Kaifeng, Michael visits a women's mosque with a female imam, a delightful scene that ends with laughter and selfies! The Qing also undertook huge cultural enterprises. At a traditional printing house where the wood blocks are hand-carved, we see how the Complete Tang Poems were reproduced - all 48,000 of them. We travel through the wintry countryside to a remote village where a hardy audience watch open-air opera in the snow and visit a painter's studio, and 'storytelling' houses in Yangzhou. In the 18th century, China was arguably the greatest economy in the world, and we get a fabulous sense of the rich culture that came with prosperity. But then came the clash with the British, in the first Opium War, when a British expedition destroyed the Qing navy and extracted territory and trading rights. We leave with a glimpse of the future. 'Every dynasty has risen and declined,' says Michael, 'and has needed new life to regenerate, and this time the catalyst was the British.' Among the ports China ceded was an almost uninhabited island, Hong Kong, one of today's greatest financial centres, and Shanghai, a small town then but now one of the greatest cities in world.

Winner of the Best Documentary Short Award, the film tells the story of four unassuming heroes who ensure no student is deprived of the joy of music. It is also a reminder of how music can be the best medicine, stress reliever and even an escape from poverty.
Since 1959, Los Angeles has been one of the few United States cities to offer and fix musical instruments for its public school students at no cost. Those instruments, numbering around 80,000, are maintained at a Los Angeles downtown warehouse by a handful of craftspeople. The film profiles four of them, each specializing in an orchestra section, as well as students whose lives have been enriched by the repair shop's work. The film concludes with a performance by district alumni.

This episode explores the palaeogeography of Earth over millions of years, and its impact on the development of life on the planet. Tyson starts by explaining that the lignin-rich trees evolved in the Carboniferous era about 300 million ago, then explains on the nature of plate tectonics that would shape the landmasses of the world and the asteroid impact that initiated the Cretaceous–Paleogene extinction event, leaving small mammals as the dominate species on earth. Earth's landmasses are expected to change in the future and postulates what may be the next great extinction event.

The film explores how artificial intelligence (AI) is catching up to us in ways once thought to be uniquely human: empathy, emotional intelligence and creativity. AI has the potential to reshape every aspect of our world – but most of us are unaware of what looms on the horizon. This documentary shows viewers what they need to know about a field that is advancing at a dizzying pace, often away from the public eye. Have AI the power to disconnect us from fellow humans? What does it mean when AI makes art? Can really AI interpret and understand human emotions? How is it possible that AI creates sophisticated neural networks that mimic the human brain?
The documentary includes interviews with global leaders, commentators and innovators from the AI field, including Geoff Hinton, Yoshua Bengio, Ray Kurzweil and Douglas Coupland, who highlight some of the innovative and cutting-edge AI technologies that are changing our world.
