Defiance (2013) is a science fiction television series developed by Rockne S. O’Bannon. The show is set in a post-apocalyptic future where Earth has been drastically transformed after the arrival of multiple alien species, known as the Votans, who have colonized the planet following a devastating war between humans and aliens.

The story takes place in the town of Defiance, built on the ruins of St. Louis, where both humans and aliens coexist, trying to rebuild civilization amidst tensions, conflicts, and power struggles. The show follows Joshua Nolan (played by Grant Bowler), a former soldier turned lawman, and his adopted alien daughter, Irisa (played by Stephanie Leonidas), as they work to maintain peace and order in this volatile environment.

Defiance blends elements of action, adventure, and drama, with intricate world-building that explores themes of survival, unity, and the consequences of war. It also combines traditional storytelling with a tie-in massively multiplayer online video game, offering a unique transmedia experience for fans. The show ran for three seasons, gaining a cult following for its creative blend of science fiction and Western motifs.
