Defiance is an American science-fiction television series. The series takes place in the future and on an Earth like no one has ever seen before. In the pilot we are introduced to Nolan, who is a local sheriff for the town of Defiance, where the rest of our characters reside. Alien creatures and humans live side-by-side, though not as harmoniously as desired, which makes it even harder for Nolan, who has an adopted alien daughter. The series is also tied-in with a MMORPG video game.
