On the edges of the Wild West, in a rugged area of Wyoming, is a frontier town where magic is openly known: HAZELDINE.

Amidst dramatic summer thunderstorms, many in Hazeldine are adjusting to new changes: Pete Steele continues his vampiric instruction with Crispin Clarion, while wizard Oz Urbaniak (with his new, disembodied partner, Fen Porter, riding shotgun in his head) and the brawny Quincey Dare sign on as ranchers with the San Toro herd. Blythe and Caleb take the next step in their courtship as the letters between banker Rodrigo and sharpshooter Seung (still disguised as "Rouge") turn serious -- and the pair find themselves spending more time together face-to-face.

As Celeste, Ianto, and George navigate the new parameters of their relationship, George tests his empathy, Ianto's Wulver compulsions threaten his newfound peace, and Celeste turns her passion for improvements to a new project.

Jenny's fears over an impending attack by the cruel Baron force Liesel to find her courage. Big city lawyer Ethan William Bradley makes a surprise visit to his childhood home (at the worst possible time).

And with the arrival of the Dalton Crescent Pack survivors, Hazeldine finds itself under a frightening quarantine. Will Doc, Nova, and Jenny be able to contain the influenza? And will Jack Solomon live long enough to see his packmates recover, with his trial fast approaching?
