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.

Professor Jim Al-Khalili investigates one of the most important concepts in the world today - information. He discovers how we harnessed the power of symbols, everything from the first alphabet to the electric telegraph through to the modern digital age. But on this journey he learns that information isn't just about human communication, it's woven very profoundly into the fabric of reality.

In this second episode, a woman recounts her journey to becoming a mouthpiece for white nationalist hate speech, work that culminates in high-profile violence and murder. Samantha confesses how she became a spokesperson on the Internet for the hate speech of one of the many white nationalist groups that swarm the United States. And this fact ended in racist violence and death during an event.
'I had to start to realize what I was supporting. Was I the victim or was I also a villain?' says Samantha, looking into the camera. Hand in hand with xenophobia, digital true crime seems to have no respite, and so it will be shown how those supremacists work with good Wi-Fi.

Odds are excellent that extraterrestrial life exists. So why haven’t we found aliens out in the galaxy? Are we looking in the wrong places? New research shows we should look closer to home, even inside our bodies. It turns out that a lot of our DNA is from a mysterious, nonhuman source. Theoretically, alien microbial life can make the journey to Earth from distant worlds, and scientists are finding some unearthly microbes in our upper atmosphere. Could it be from outer space? Could we be part alien? It’s even possible alien life is already here as digital life forms, hiding inside our technology.

Technology is evolving from an external tool we wield when needed to an always-there presence that is with us, on us, even inside of us. As we become more and more wired, are we becoming digital devices ourselves? In this episode meet a Swedish mom who implanted an RFID chip as a lifestyle choice; a filmmaker who lost his eye in a gun accident and replaced it with a camera; and the so-called "world most connected man," who uses between 300-700 tracking and life logging systems to monitor every aspect of his life.
