The first of its kind, Defiance is the quintessential media property created with Igniters in mind— sparking their imaginations while encouraging them to truly open their minds to what is possible.
Set on Earth thirty years in the future, Defiance is a story of courage and survival on a new frontier where humans and aliens must band together to defend their very existence. United they stand. Divided they fall. It’s do or die in the small town of Defiance.
