Firstly there is the small matter of Dark Matter.
Dark matter is a hypothetical kind of matter that cannot be seen with telescopes but would account for most of the matter in the universe. The existence and properties of dark matter are inferred from its gravitational effects on visible matter, radiation, and the large-scale structure of the universe. Other than neutrinos, a form of hot dark matter, it has not been detected directly, making it one of the greatest mysteries in modern astrophysics.
Of course, I don't actually mean that kind of Dark Matter, but rather the Scyfi channels dark spaceship thriller. Basically A group of six people with no memory of who they are and where they came from wake up on a starship. Naming themselves "One" through "Six" in order of their awakening, they stabilize their vessel and begin trying to figure out what happened to them.
In my opinion this is a fascinating science fiction story that is set in a parallel now. We have a group of people around the world are suddenly linked mentally, and must find a way to survive being hunted by those who see them as a threat to the world's order.
To properly tell the international aspects of the story, filming took place almost entirely on location around the globe in nine cities located in eight countries: Chicago, San Francisco, London, Berlin, Seoul,Reykjavík, Mexico City, Nairobi and Mumbai. Production on the series began in June 2014 in San Francisco.
Initial writing was split between the Wachowskis and Straczynski.
