As the story of “Defiance” resumes, the lives of the townspeople are in drastic turmoil.  The Earth Republic has assumed control of the town, with far-reaching consequences including a new mayor.  Nolan traverses the badlands to find a lost Irisa, Amanda has an unexpected new role in the town as she searches for Kenya and the Tarr family desperately tries to keep control of their criminal empire in the midst of dramatic changes. 

James Murray joins the cast in the integral role of Mayor Pottinger, the new mayor of Defiance.  Appointed by the Earth Republic, Pottinger is shrewd, polished and charming; he quickly wins the trust of most people he meets. But his civilized veneer hides a ruthless pragmatist who traffics in information and secrets, and mercilessly punishes those who defy him.  Pottinger sees people as tools to be exploited or prizes to be won; his latest object of desire is ex-mayor Amanda (Benz).
