History keeps repeating itself when Wynonna has to make an impossible choice. Waverly and Nicole visit a jeweller and a familiar face returns to Purgatory.

A mysterious woman who knows a little too much about the Earps arrives on the Homestead with a special mission for Wynonna and Waverly. The rest of the team must wrangle a deadly fire witch.

Wynonna has a run in with Revenants that leads her to an unexpected revelation about the curse. Waverly meets an important figure from her past, and Nicole tries to evacuate Purgatory - before it's too late.

The Pledge Moon looms over Purgatory as Wynonna and Waverly must find a way to end the family curse before their demonic foe puts an end to the Earp line - and humanity - once and for all.
