Tamara Duarte

Conditions in the town grow worse as a Trouble turns darkness deadly. Can Nathan get the power back on in time?

Nathan enters the Void, whose terrors include an old adversary. Audrey and Duke deal with a newly-Troubled individual who's out for revenge.

Nathan must make common cause with an enemy. Audrey and Duke try to find a way to free him, and Dave wrestles with Croatoan's control.

Walt deals with the fallout of the shooting of Tyler Malone (guest star Nick E. Tarabay) and the arrest of oil rig worker Trot Simic (guest star Aaron McPherson), while an injured Henry goes on the run with Gab Langton in search of a mysterious Crow Medicine Woman (guest star Tantoo Cardinal). Meanwhile, new deputy Zach Heflin (recurring guest star Barry Sloane) puts his job on the line when a confrontation with a suspect turns violent.

When a Cheyenne woman, Gabriella "Gab" Langton (guest star Julia Jones) is assaulted on the Rez by oil rig workers, both Mathias and Walt find themselves unable to pursue the suspects due to issues of jurisdiction. But Cady is determined and seeks the help of a Federal Prosecutor to bring Gab's assailants to justice.

Walt gets more bad news from the mayor. As Walt learns what’s behind the lawsuit, both Henry and Cady face tribal rituals. And Vic does a strange favor in the season finale.
