The second episode of the series immerses the viewer in a fascinating journey through the history of life on our planet, focusing on the evolution and adaptation of life in the seas. It begins billions of years ago, when the Earth was an inhospitable place and life was impossible on the surface due to a hostile environment. The documentary highlights how, beneath the waves, life began to flourish, protected from storms and other elements of nature. It addresses the development of photosynthesis by plankton and how this led to a significant change in the Earth's atmosphere, allowing the emergence of animal life.
This visually stunning narrative chronicles the evolution of various forms of marine life, from the earliest complex life forms to the appearance of the first fish and cephalopods. The documentary shows how marine life has influenced terrestrial life, emphasizing the impact of the 'greening' of planet Earth.

The second episode takes a look at how humans have always been voyagers and explorers, leaving the comfort of native shores to explore. Neil DeGrasse Tyson will show us a long-term vision of humanity's future worlds.

It is 1918 and the end of WWI. Millions have died, and the world is exhausted by war. But soon a new horror is sweeping the world, a terrifying virus that will kill more than fifty million people - the Spanish flu. Using dramatic reconstruction and eyewitness testimony from doctors, soldiers, civilians and politicians, this one-off special brings to life the onslaught of the disease, the horrors of those who lived through it and the efforts of the pioneering scientists desperately looking for the cure.
Narrated by Christopher Eccleston, the film also asks whether, a century later, the lessons learnt in 1918 might help us fight a future global flu pandemic.

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.
