Set in the near future, this epic drama introduces a completely transformed planet Earth, inhabited by the survivors of a universal war. Forced to co-habitate, the disparate group struggles to build a new society among the devastation. At the center of this world is Lawman Jeb Nolan (Grant Bowler, True Blood), who enlists the help of deputies and occasionally some civilians in the struggle to maintain law and order in the town and region. To survive in this unforgiving landscape, it will take strength. It will take will. It will take Defiance.
