By the year 2046 Earth has been radically changed both environmentally and culturally after an alien race settles on the planet’s surface. This series follows Joshua Nolan (Grant Bowler) and his adopted alien daughter Irisa (Stephanie Leonidas), as they live each day in Defiance; a city (formerly St. Louis) ran by a Mayor Amanda Rosewater (Julie Benz) where humans and extraterrestrials coexist. Nolan assumes the position of Defiance’s Lawman and with it comes trouble as he polices both humans and aliens alike. Defiance is developed by Rockne S. O’Bannon who is best known for creating the cult sci-fi seriesFarscape.
