Northern Montana: 1881.
A member of an all-female “rough rider” circus kills a preacher’s son when he and his gang attack one of her friends.
The town’s sheriff knows that she was acting to save a life but is forced to raise a posse to track down the showgirls who have fled into the iron-cold wilderness of the Pacific Northwest.
The pursuit soon turns to a series of running battles – in one of which, the sheriff’s son is killed. Urged on by the fire and brimstone preacher, the sheriff turns from reluctant pursuer to vengeful hunter.
Knowing that posse will never let them be, the performer responsible for killing the preacher’s son gives her group the slip and surrenders.
She is taken back to town and – after a show trial in which the preacher accuses her and the rest of her troupe of “beguiling us with black magic” – she is burned at the stake as a witch by the townsfolk.
But retribution the hammer of retribution smites the town of Paradise Falls when the rough-riders return, hellbent on its destruction.
A bloody battle ensues that sees the down burned to the ground, ending with the rough riders making their final stand in the church.
All but one of the women are killed when the church is set afire by the townsfolk. Wounded - probably dying - she shoots the sheriff dead from a great distance before turning her horse back into the wilderness.
