Reckless and reluctant gunslinger Wynonna Earp and her team of outmatched outsiders return to face the demon who cursed the Earp family before he destroys the Ghost River Triangle - and the world.
Now that any paranormal entity can enter the Ghost River Triangle, Wynonna Earp and her crew - sister Waverly, Waverly's girlfriend Nicole, centuries old Doc Holliday and Black Badge Agent Dolls - must defend Purgatory from a whole new slew of demons, ghosts, and assorted evils. Thankfully, Wynonna's one-liners remain.
After years away, Wynonna Earp has traveled back to her home town of Purgatory to reluctantly take on the role destined for Wyatt Earp's heir: Demon protector. Her enemy: Revenants, the resurrected (and twisted) souls of the criminals Wyatt Earp once took down. Using only her wits and her wit, Wynonna, along with sister Waverly, associate Agent Dolls and Wyatt's cursed-with-immortality-best-friend Doc Holliday, must try to stop the Revenants from taking over the town - and escaping into the world.
