The story begins with Tyson sitting at a campfire, and telling how the wolf changed through artificial selection, and selective breeding into the dog breeds around today. He then enters the Ship of Imagination, and explains natural selection with the process that helped to create the polar bears. Along the way he talks about DNA, genes and mutation. Next he goes to a forest and describes the Tree of life, this leads him to discussing the evolution of the eye. He then discusses extinction, by going to a monument called the Halls of Extinction, dedicated to the broken branches of the tree of life. Explaining the five great Extinction events. He then tells how some life has survived, and then focuses on the tardigrade. From there he talks about what other kinds of life might have been created on other worlds. He then goes to Saturn's moon Titan. From there he speculates about life and how it first began. He then returns to Earth and tells about abiogenesis and how life changed and evolved. The show ends with an animated sequence from the original series of life's evolution from one cell to humans.

The film examines strange shapes of the universe, such as the 'Eye of God', the hexagon on Saturn, and the 'face' on Mars. One of Saturn's moons is a Star Wars lookalike. Could the strange patterns of the universe now solve mysteries that have haunted mankind since ancient times?

The magnificent ringed planet Saturn, along with its more than 80 moons, forms the most dynamic planetary system in our neighborhood. With underground oceans and protective magnetic fields, experts are exploring how this collective of satellites has the potential to rewrite the rules of the Solar System.
The closer that we look, the more we see these extraordinary moons like worlds of their own -- so dynamic, so Earth-like. Almost a billion miles from the Sun, these icy worlds could be home for Life 2.0. The moons of Saturn offer possibly the best chance of finding extraterrestrial life in our solar system. With each new mission, we get closer to unraveling the mysteries of Saturn's moons.

The 8th episode reviews Giovanni Cassini's life. His observations of Saturn and its moons would have an enduring effect on the scientific world. Neil deGrasse Tyson also narrates the mysterious untold story of the scientist who figured out how to go the Moon while fighting for his life in a WWI trench. Aleksandr Shargei changed his name to Yuri Kondratyuk out of fear for his life and wrote a manuscript on rocket motion and space colonization. This letter would end up capturing the attention of an engineer working on the Apollo program, John Houbolt, and would made the Apollo Mission possible.
We will also know the saga of the twenty-year long odyssey of Cassini-Huygens spacecraft, a robotic explorer ordered to commit suicide on another world.
