The film reveals the secret story behind one of the greatest intellectual feats of World War II, a feat that gave birth to the digital age.
In 1943 Bill Tutte, a 24-year-old maths student and a GPO engineer called Tommy Flowers combined to hack into Hitler's personal super code machine - not Enigma but an even tougher system, which he called his 'secrets writer'. Their break turned the Battle of Kursk, powered the D-day landings and orchestrated the end of the conflict in Europe. But it was also to be used during the Cold War - which meant both men's achievements were hushed up and never officially recognised.

The film is focused on and celebrating the radical changes in postwar Britain under the Labour government of Clement Attlee, which came to power in 1945. Relying primarily on archive footage and interviews, and without a narrative voiceover, the documentary recounts the endemic poverty in prewar Britain, the sense of optimism that followed victory in World War II and the subsequent expansion of the welfare state, founding of the National Health Service and nationalisation of significant parts of the UK's economy.
The film documents the extent to which these achievements, as the filmmaker Ken Loach sees them, have since been subject to attack in the decades that followed, particularly under the Conservative governments of Margaret Thatcher in the 1980s

An Ice Age relic found in a mysterious cave is evidence of prehistoric humans' connection to the supernatural. Using cutting-edge tech, experts investigate this 40,000-year-old treasure to reveal why it was made and the long-lost myths it represents.
In the summer of 1939, a team of explorers unearthed hundred of mammoth ivory fragments within a cave in Germany. Due to the start of World War II, the explorers were forced to abandon their findings, and the fragments laid forgotten in a museum. Decades later, as archeologists began piecing the fragments together, an extraordinary artifact emerged -- a figure with both animal and human features, now known as the 'Lion man.'

It's June 1942 and the world's fate is about to be decided by a handful of pilots and their untested aircraft. Experience an inside look at the Battle of Midway, captured through rarely seen battle footage and first-hand accounts from its hero dive-bombing pilot, "Dusty" Kleiss. This is an hour-by-hour recount of one of the most pivotal conflicts of the 20th century. Take a closer look at how this desperately needed victory came about through the design of U.S. air planes, the skill of the pilots, the element of surprise, and a stroke of luck.

Between 1850 and 1950, three cataclysmic revolutions shook China to the core, but out of them, today's China emerged. The film begins in Canton with the meeting of a US missionary and a Chinese student. Inspired by the Christian story and calling himself God's second son, Hong unleashed the bloodiest war of the 19th century, the Taiping Rebellion.
As imperial China weakened, foreign influence grew. Treaty ports expanded, bringing growth and wealth, trams, railways and western sensibilities. But this provoked another surge of violence, the Boxer Rebellion, an attack against the foreigners, which was crushed by those same foreigners, who extorted a huge indemnity - $60 billion in today's money.
Then in 1912, the empire fell, and many groups contested China's future. In World War I, China sent 100,000 men to the western front, only to be humiliated at Versailles when German colonies in China were handed to Japan. Between the two world wars, the disparity between rich and poor, city and countryside increased. We visit Hong Kong's Peninsular Hotel in the jazz age and then follow Mao on the Long March to Yan'an, the heartland of revolution.
World War II came to China two years earlier than it did in the west. Wood talks to a survivor of the Japanese massacre of Nanjing in 1937 and then charts the triumph of the communists, before ending the story with Mao's death and the boom time of the last 30 years. The series ends with the warmth of the Chinese family and, at Beijing's Altar of Heaven, a final haunting glimpse of eternal China.

Episode three explores the mind of one of the most fanatical of all Nazis and the insight that gives into the psychology of dictatorship. Hess is brought to Nuremberg from the UK where he had flown 4 years earlier much to the bemusement of the British. Overy explains that they must have quickly realised he was not normal. In the intervening time Hess’s mental state has further deteriorated and when interviewed by Chief Interrogator Colonel John Amen proclaims amnesia. Chief Interpreter Richard Sonnenfeldt explains that they brought in Göring to confront Hess but that he too failed to make an impression.
Psychopathologist Prof. Edgar Jones proposes Hess’s behaviour patterns may be his way of escaping reality as he is forced to face the extent of the atrocities and choose between accepting his part of the blame or forsaking his Führer. However, as history Professor Robert Gellatel explains it is difficult to construct a case against Hess as he was imprisoned in England when the worst of the atrocities were carried out so British Prosecutor Mervyn Griffith-Jones must argue a conspiracy charge linking the pre-1939 persecutions to the post-1939 atrocities and a crimes against peace charge proving the flight to Scotland was merely a ruse.
