Meet Wynnona Earp, great granddaughter of gun-slinging legend Wyatt Earp and Demon Protector at large. She's about to raise a little hell with a colt .45 pistol customised with a 12 inch barrel which she calls 'Peacemaker'. You better hope she doesn't point this demon killing gun in your direction, because Wynnona never misses her target.

The Earp family has a curse on them that means when each new heir turns 27, a group of zombies called 'Revenants' com calling. An Wynnona has just turned 27. Only Wynnona and her dysfunctional posse can kill these zombies and send them back to hell...so join them as they try to bring the paranormal to justice in their hometown of Purgatory.
