After killing the last of the Seven, Wynonna wonders what to do with her life now that she's had her revenge. A new opportunity soon arises when Doc tracks down Constance and needs help dealing with the Stone Witch. Meanwhile, Waverly approaches Nicole while Neadley helps Xavier blend in with the community.

Wynonna and Xavier learn that there's a revenant with a weapon that Bobo fears, and goes looking for him. Meanwhile, Doc considers leaving Purgatory, and Wynonna learns what Xavier has been hiding.
