Join us on an unforgettable voyage through one of the most desolate periods in human history as the rulers, conflicts, and cataclysmic societal breakdown of Early Middle Ages are brought to light. At its height in the second century A.D., the Roman Empire was the beacon of learning, trade, power and prosperity in the western world. But the once-powerful Rome--rotten to the core by the fifth century--lay open to barbarian warriors who came in wave after wave of invasion, slaughtering, stealing, and ultimately, settling. As chaos replaced culture, Europe was beset by famine, plague, persecutions, and a state of war that was so persistent it was only rarely interrupted by peace.
The documentary profiles those who battled to shape the future, from the warlords whose armies threatened to case the demise of European society, like Alaric, Charles the Hammer, and Clovis; to the men and women who valiantly tended the flames of justice, knowledge, and innovation including Charlemagne, St. Benedict, Empress Theodora, and other brave souls who fought for peace and enlightenment. It was in the shadows of this turbulent millennium that the seeds of modern civilization were sown.

In January, 2015, American rock climbers Tommy Caldwell and Kevin Jorgeson captivated the world with their effort to climb the Dawn Wall, a seemingly impossible 3,000 foot rock face in Yosemite National Park, California. The pair lived on the sheer vertical cliff for weeks, igniting a frenzy of global media attention. But for Tommy Caldwell, the Dawn Wall was much more than just a climb. It was the culmination of a lifetime defined by overcoming obstacles. At the age of 22, the climbing prodigy was taken hostage by rebels in Kyrgyzstan. Shortly after, he lost his index finger in an accident, but resolved to come back stronger.
When his marriage fell apart, he escaped the pain by fixating on the extraordinary goal of free climbing the Dawn Wall. Blurring the line between dedication and obsession, Caldwell and his partner Jorgeson spend six years meticulously plotting and practicing their route.

Dr Nigel Spivey explores how art influences life by tracing the development of the image from cave paintings to our modern obsession with images. Dr. Spivey begins his investigation by travelling to the Cave of Altamira near the town of Santillana del Mar in Cantabria, Spain, where in 1879 a young girls exclamation of 'Papa, look, oxen!' to her father, local amateur archaeologist Marcelino Sanz de Sautuola, is explained to have meant that Maria had just become the first modern human to set eyes on the first gallery of prehistoric paintings ever to be discovered.

Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link. The team overcomes huge obstacles as it attempts to drill 1,500 metres beneath sea level to pull up rock from the Chicxulub crater. Meanwhile, paleopathologist Professor Alice Roberts travels the globe meeting top scientists and gaining exclusive access to a mass fossil graveyard in New Jersey - believed to date from the same time the asteroid hit. Alice also treks by horseback across the remote plains of Patagonia, to see if the effects of the asteroid impact could have wiped out dinosaurs across the world - almost immediately.

August 6th 1945 marked the start of a terrifying new episode in human history. This documentary marks the 70th anniversary of the day when the world's first atomic bomb was dropped on the Japanese city of Hiroshima by a Boeing B-29 USAF Superfortress bomber, nicknamed Enola Gay after the pilot's mother". Up to 80,000 people - 30 per cent of the population - were killed by the blast and resulting firestorm and over 70,000 were injured. This documentary gives a minute-by-minute account of what happened on that fateful day, through the testimony of people who were there and rarely-seen archive footage from the time. Made on location in Hiroshima and the USA, it features unique interviews with eyewitnesses who have seldom, if ever, spoken about the experience. Several of them are no longer alive, they include the last surviving member of the crew of the Enola Gay - navigator Dutch Van Kirk who died in July 2014.

Sir David Attenborough reveals the findings of one of the most ambitious scientific studies of our time - an investigation into what is happening to our oceans. He looks at whether it is too late to save their remarkable biodiversity. Attenborough explores some of the ways in which we are affecting marine life - from over-fishing to the acidification of sea water. The film also uncovers the disturbing story of how shipping noise is deafening whales and dolphins, affecting their survival in the future.
