Attenborough's journey continues in Canada's Rocky Mountains, where fossils document an explosion in animal diversity never seen before or since. Travelling from there to North Africa, the rainforests of Australia and the east coast of Scotland, Attenborough discovers how animals evolved to conquer not only the oceans but also the land and air. These remote and fascinating creatures are brought to life as never before with the help of cutting-edge scientific technology and photorealistic visual effects. From the first large predators to the first legs on land, these were creatures that evolved the traits and tools that allow all animals, including ourselves, to survive to this day.

Is there anyone out there? Astronomers have been pointing their radio telescopes at the skies for decades trying to pick up alien signals, so far without success. But now there's a new way of looking for aliens. Hitch a ride with Dr Graham Philips as he joins astronomers trawling through the galaxy looking for signs of extra-terrestrial intelligence.

Are rising temperatures driving Earth's ecosystems past a point of no return? We have promising technologies that put solutions within our grasp. Scientists are exploring solutions: from geoengineering to sucking carbon out of the air to cloud brightening, as means to cool the planet. Cutting-edge solutions and high-risk measures. But would they work? And what are the risks of engineering Earth's climate?

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.

Eternal life is humanity’s oldest dream. It may be finally coming true. Today, at least in the West, the quest for immortality has shifted from the metaphysical to the technical and the scientific. In this film we will investigate the advancement of this research in laboratories around the world. With cryonics technology improving, human cloning now possible, mind uploading and digital brain simulation thriving, reversing the aging of cells and organs feasible, immortality may seem right around the corner. In some countries, such as the US, Russia and Europe, private companies are financing and promoting the promise of immortality or at least a longer life expectancy. Are they selling a reality or utopia? We will meet scientists, neurophysiologists, computer specialists, geneticists, and biologists, and also hopefuls of immortal life, futurists, sociologists and businessmen. We will film different research laboratories and cities built for the aging; we will interview the experts as well as the anonymous men and women who speak about their relationship with life and death and those who simply embody it.

Filmed across six continents, this docuseries uses cutting-edge camera technology to capture animal's nocturnal lives revealing new behaviours filmed in full color like never before. In the first episode, we will see how after dark on Kenya's Maasai Mara grasslands, a lioness won't rest until she finds the young cubs she's lost.
