The turbulent life of soul and blues singer, the late Joe Cocker. A former gas fitter from Sheffield, catapulted to world stardom in 1969 at Woodstock with his legendary performance of the Beatles song, 'A Little Help from My Friends'. But in the early 1970s, Joe Cocker's inner demons nearly killed him. Overcoming his struggles with alcohol and drugs, he rebuilt his reputation as 'one of the great primal rock and roll vocalists of all time' (Billy Joel).

Leading authority on the Middle Ages, Professor Robert Bartlett, presents a series which examines the way we thought during medieval times. In the second episode, Bartlett unearths remarkable evidence of the complex passions of Medieval men and women. The Church preached hatred of the flesh, promoted the cult of virginity and condemned woman as the sinful heir to Eve. Yet this was the era that gave birth to the idea of romantic love.

We call them 'man’s best friend', but their story is almost as old as man himself. Our very first friend in the world, they have walked by our side for over 20,000 years, helping us to hunt for food and offering us companionship and protection. Man’s First Friend is an epic new primetime documentary event that combines natural history, science and anthropology to explore the enduring relationship between humankind and dogs, how the two species have co-evolved together, where did they come from to take such a prominent position in our lives, and how did we learn to harness their unique talents.
The film takes viewers on an extraordinary journey through some of the most remote locations in the world to answers these questions and more. It highlights what dogs are capable of: from the Pariah dog in India who protects her owner’s banana plantations from daily attacks by Black-headed Monkeys; to Kenyan Bloodhounds trained to track ivory poachers. Dogs comfort us, relieving loneliness and helping us cope with old age.

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.

Time travel is not forbidden by the laws of nature, but to build a time machine, we would need to understand more about those laws and how to subvert them than we do now. And every day, science does learn more. In this film Horizon meets the scientists working on the cutting edge of discovery - men and women who may discover how to build wormholes, manipulate entangled photons or build fully functioning time crystals. In short, these scientists may enable an engineer of the future to do what we have so far been only able to imagine - to build a machine that allows us travel back and forward in time at the touch of a button. It could be you! Science fiction? Watch this film.

Bitcoin is the world's leading virtual currency, but unlike real money, it is not backed by a government or properly regulated. Bitcoin is exchanged and held digitally by users - which is attractive to criminals selling drugs, pornography and arms. But now Bitcoin is moving into the mainstream and being openly marketed as an investment opportunity. The film investigates what Bitcoin is and what it means, going inside a Bitcoin mine in Iceland - where currency is made - and spending time with the Bitcoin millionaires of Silicon Valley.
The programme also hears from others who have been scammed out of their life savings and investors who think the cryptocurrency is an enormous scam and that the writing is on the wall. Around the world, authorities are sounding the alarm that Bitcoin is too risky - is it too late, or too crazy, to try to become a Bitcoin millionaire?
