When a mysterious bus full of sexy strangers rolls into town, Wynonna must figure out why they’re in Purgatory before the entire town falls under their spell.
Sheriff Nedley, under the glamor spell of a vampire, permits a van-load of vampires into Purgatory. At the same time, unsuspecting Purgatory bar patrons are massacred and were rearranged in special configurations as an offering to Bulshar. While investigating the mass murder, Nicole endures the makings of a panic attack, much to Waverly's concern. While taking a breather in the bathroom, Nicole falls under the spell of vampire Petra, who also bedazzles Waverly.
Doc wakes up in a bar, from a nightmare. He finds Jeremy in his basement, and pink fog envelops the place. Both of them traverse upstairs to find the entire bar massacred by vampires. Doc is captured by the vampires; Jeremy is converted.
Dolls nearly falls for it as well, but because of his reptilian DNA is able to fend it off; Doc is abducted, tied up, and thrown into the vampire van, and nearly shanghaied into vampire service by Contessa, who has a history with Doc, before escaping. Wynonna, after seeing pink fog come from the barn, enters and kills a vampire in there, and when she returns to her household to warn Waverly, Nicole and Jeremy, she ends up being knocked out by the glamoured trio and thrown into a coffin, ready to be served up to Bulshar as an offering.
However, Dolls finds Wynonna in the basement of the house, and together they fashion stakes from chairs, which they use to vanquish almost all of the vampires during an impromptu party-crashing.
Once Petra is taken down, the spell is broken and Wynonna's team throws down. They save the head vampire for last, and Wynonna sends him to Bulshar with a message: she's coming for him. The next day, Nicole returns to the scene of the massacre and has a startling realization: she thinks she was a survivor of the Cult of Bulshar. And while Wynonna takes Waverly on a drive to tell her about their mother, the car skids off the road, flips over, and rolls down a slope. Waverly is shortly thereafter dragged from the car by an unseen figure, screaming for her sister.
