SETTING: 70 million years ago in Europe, near present-day Romania. Pod, a male pyroraptor, is alone in the world after his sisters die in a tidal wave that sweeps him out to sea. After landing on an island populated with dwarf-sized dinosaurs, Pod discovers that he's become the apex predator. But, Pod learns it's lonely at the top.

This episode covers the nature of how life may have developed on Earth and the possibility of life on other planets. Tyson begins by explaining how the human development of writing systems enabled the transfer of information through generations, describing how Princess Enheduanna ca. 2280 BCE would be one of the first to sign her name to her works, and how Gilgamesh collected stories, including that of Utnapishtim documenting a great flood comparable to the story of Noah's Ark. Tyson explains how DNA similarly records information to propagate life, and postulates theories of how DNA originated on Earth, including evolution from a shallow tide pool, or from the ejecta of meteor collisions from other planets. In the latter case, Tyson explains how comparing the composition of the Nakhla meteorite in 1911 to results collected by the Viking program demonstrated that material from Mars could transit to Earth, and the ability of some microbes to survive the harsh conditions of space. With the motions of solar systems through the galaxy over billions of years, life could conceivably propagate from planet to planet in the same manner. Tyson then moves on to consider if life on other planets could exist. He explains how Project Diana performed in the 1960s showed that radio waves are able to travel in space, and that all of humanity's broadcast signals continue to radiate into space from our planet. Tyson notes that projects have since looked for similar signals potentially emanating from other solar systems. Tyson then explains that the development and lifespan of extraterrestrial civilizations must be considered for such detection to be realized. He notes that civilizations can be wiped out by cosmic events like supernovae, natural disasters such as the Toba disaster, or even self-destruct through war or other means, making probability estimates difficult. Tyson describes how elliptical galaxies, in which some of the oldest red dwarf stars exist, would offer the best chance of finding established civilizations. Tyson concludes that human intelligence properly applied should allow our species to avoid such disasters and enable us to migrate beyond the Earth before the Sun's eventual transformation into a red giant.

The terrorist group Boko Haram is responsible for thousands of deaths in Nigeria. Now, the government is determined to drive these militants from the country. But is the hunt for insurgents causing as much harm as it's preventing? Former Navy SEAL and new VICE correspondent Kaj Larsen travels to Nigeria to see what this cat-and-mouse game means for the people caught in the middle of the fight. 'Unnatural Selection': For centuries, scientists have been working to change the genetic traits of plants and animals. Now, the new gene-editing method CRISPR has made that process astonishingly simple - so simple it could easily be used on humans. Isobel Yeung reports from Brazil, Scotland, China and the U.S. on the technological advances that could reshape evolution as we know it.

A wholly innovative, original, and vital history lesson, with pioneering animation, Waltz With Bashir delivers its message about the Middle East in a mesmerizing fashion. Director Ari Folman's animated quasi-documentary follows the filmmaker's emotional attempt to decipher the horrors that unfolded one night in September of 1982, when Christian militia members massacred more than 3,000 Palestinian refugees in the heart of Beirut as Israeli soldiers surrounded the area". Folman was one of those soldiers, but nearly 20 years after the fact, his memories of that night remain particularly hazy. After hearing an old friend recall a vivid nightmare in which he is pursued by 26 ferocious dogs, Folman and his friend conclude that the dream must somehow relate to that fateful mission during the first Lebanon War. When Folman realizes that his recollections regarding that period in his life seem to have somehow been wiped clean, he travels the world to interview old friends and fellow soldiers from the war. Later, as Folman's memory begins to emerge in a series of surreal images, he begins to uncover a truth about himself that will haunt him for the rest of his days.

Travel from the inner solar system to the Kuiper Belt and explore the moons surrounding the planets of the solar system. Many of these moons that were once unknown are now on the cutting edge of astronomical study. Some burst with volcanic fury another spews icy geysers and others offer the possibility of alien life. Are these strange worlds simply hostile environments unfit for humans or do other possibilities exist? Cutting-edge computer graphics are used to bring the universe down to earth and to imagine what kind of life forms might evolve in alien atmospheres.

In this episode he traces India in the days of the Roman Empire. In Kerala the spice trade opened India to the world, whilst gold and silk bazaars in the ancient city of Madurai were a delight for visiting Greek traders. From the deserts of Turkmenistan Michael travels down the Khyber Pass to Pakistan to discover a forgotten Indian Empire that opened up the Silk Route and at Peshawar built a lost Wonder of the World.
