Be it foxes on city streets or wolves on the tundra, canines rely on sharp senses, athleticism and fierce determination to punch above their weight. But the real secret of their success is much more surprising. It's a story of their intimate side. It's what makes every dog, from pet pooch to wild dogs, one of the family.

The 80s was also an age of innovators and icons, of style and substance. In this chapter, Dylan Jones celebrates some of the stars who created the timeless legacy of the 1980s.

It also features rarely seen archive television footage from the BBC vaults, including Terry Wogan interviewing Grace Jones, Bruce Springsteen on the Old Grey Whistle Test and Adam Ant performing his own stunts in a behind-the-scenes look at the making of the Prince Charming video.

Marc-André Leclerc climbs alone, far from the limelight. On remote alpine faces, the free-spirited 23-year-old Canadian makes some of the boldest solo ascents in history. Yet, he draws scant attention. With no cameras, no rope, and no margin for error, Leclerc's approach is the essence of solo adventure.
Nomadic and publicity shy, he doesn't own a phone or car, and is reluctant to let a film crew in on his pure vision of climbing. Filmmaker Peter Mortimer sets out to make a film about Leclerc but struggles to keep up with his elusive subject. Then, Leclerc embarks on a historic adventure in Patagonia that will redefine what is possible in solo climbing.

The film follows the story of Abu Zubaydah, the first high-value detainee subjected to the CIA's program, of Enhanced Interrogation Techniques (EITs), later identified as torture by those outside the agency. Having never been charged with a crime or allowed to challenge his detention, Zubaydah remains imprisoned at Guantánamo Bay in Kafkaesque limbo, in direct contravention of America’s own ideals of justice and due process.
Twenty years on, The Forever Prisoner reveals the origins of the clandestine operations that led the United States, in the 'War on Terror,' on a path of cruelty, deceit, and self-deception. With first-hand accounts from the two interrogators to question Abu Zubaydah, a shocking interview with the chief architect of EITs, and an interview with Daniel Jones, former Senate Investigator, the film uncovers the incompetent and deceptive practices that the U.S. government followed in order to expedite and legalize EITs in the aftermath of 9/11. As a result, torture as a government policy was authorized by the United States for the first time in history.
